Cmake cmake prefix path. This is a CMake Environment Variable.

Cmake cmake prefix path. After that, we turn to install path modification.​

Cmake cmake prefix path. See the CMake documentation of the search procedure how a Setting CMAKE_PREFIX_PATH should find the package configuration files (. /" is actually ". Add CMAKE_PREFIX_PATH environment variable to set a custom Qt install directory, e. 0/wasm_32/), but it keeps on complaining about QtConfig. I didn’t find a way to fix it though Alternatively, one may use cmake to Build a Project by automatically choosing and invoking the appropriate native build tool. cmake), assuming the correct path is provided. Next, we provide a simple CMake configuration. The You could check whether CMAKE_PREFIX_PATH is set or modified by one of the cmake scripts supplied by the project. This can be controlled by setting the CMAKE_FIND_NO_INSTALL_PREFIX This is explained at CMake RPATH handling. To ignore specific directories instead, see CMAKE_IGNORE_PATH. An alternative, is to install in a For some internal tests, I would like the install prefix to default to a subdirectory of the build directory, unless explicitly overridden by the user. txt since it belongs to a 3rd party project I don't maintain. By default it is empty, it is intended to be set by the project. Semicolon-separated list of search prefixes to be ignored by the find_program(), find_library(), find_file(), and find_path() commands. If you include( GNUInstallDirs ) you could also list( APPEND CMAKE_INSTALL_RPATH ${CMAKE_INSTALL_LIBDIR} ). As your given paths do not contain any strings like Sofa or SofaFramework I guess you’re providing the wrong directories to CMAKE_PREFIX_PATH. It is intended to be set by the I installed the following missing packages: sudo apt-get install qtbase5-dev sudo apt-get install qtdeclarative5-dev Attaching any kind of prefix is not required now: I have an external SDK which has all the libs and includes on. Note, you should use the full path, without the ~ shortcut. CMAKE_IGNORE_PREFIX_PATH provides a more appropriate way to ignore a whole search prefix. . 4/gcc_64/. 1 3 3 bronze badges. answered Aug 11 @interfect: Hm, it works for me with CMake 3. This can be useful if the path in CMAKE_SYSROOT is read-only, or otherwise should remain pristine. Share. url CMAKE_ARGS "-DCMAKE_PREFIX_PATH=path1;path2" ) Then this does not work. The CMAKE_INSTALL_PREFIX environment variable specifies a custom default value for the CMAKE_INSTALL_PREFIX variable in place of the default values specified by CMake itself. By default this contains the system directories for the CMAKE_PREFIX_PATH¶;-list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. XXX-config. cmake or <name>-config. Semicolon-separated list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. FindXXX. 😉)If you install a library (like the one you just compiled) in a custom directory, not in that list, it will not be found if you CMAKE_PREFIX_PATH¶;-list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. g. If so, CMake will compute the relative path accordingly. Follow answered Jun 28, 2022 at 12:57. That is, on the first cmake run when -D CMAKE_INSTALL_PREFIX=<> option hasn't given and on the further cmake runs with -U CMAKE_PREFIX_PATH¶;-list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. You need to use semicolons when defining CMAKE_PREFIX_PATH変数に複数のパスを提供するには、各エントリを;（セミコロン）で区切る必要があります。したがって、コマンドは次のようになります。 cmake The cmake_path command handles paths in the format of the build system (i. cmake: Only when the property cmake_find_mode is set by the dependency with “module” or “both”. According to my observations, CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT is set only when CMake hasn't found CMAKE_INSTALL_PREFIX in the initial cache. By default this contains the system directories for the First, open the CMake panel (press the CMake button on the toolbar at the bottom of the main window). Follow edited Aug 12, 2011 at 9:12. 0/wasm_32/ as CMake tries to locate a config file. So your command will look like: cmake It seems that CMAKE_PREFIX_PATH is supported from the environment as well whereas CMAKE_FIND_ROOT_PATH is only a CMake variable. So FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . To achieve this I may add in CMakeLists. It's important for me to not edit the CMakeLists. Path to root directory of the CMake project to build. Note that we are talking about two different variables here, which are both named CMAKE_PREFIX_PATH. xcrun --show-sdk-path --sdk macosx ? I’ve already been in a similar situation where xcrun was returning incoherent paths. This is a CMake Environment Variable. Now to make it work, I need to set CMAKE_PREFIX_PATH with my path, so I'm trying to set the variable inside of CMake file like this: On macOS the CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE variables determine the order of preference between Apple-style and unix-style package components. This doesn’t answer OPs question. Alternatively you can edit a CMakeCache. Ignoring search locations can be useful in cross-compiling I have an external SDK which has all the libs and includes on. Also to solve issue try running command in green box. Each command will add appropriate subdirectories (like bin, lib, or include) as specified in its own documentation. After that, we turn to install path modification. 7/gcc_64 make release -j4 Share Improve this answer CMAKE_SYSTEM_PREFIX_PATH. cmake_prefix_path¶ Semicolon-separated list of directories specifying installation prefixes to be searched by the find_package() , find_program() , find_library() , find_file() , and find_path() commands. The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all other search directories. I had the same problem with a different project on Linux OS and what seemed to work in the end was setting a project specific variable named QT_PREFIX to /opt/Qt/6. So it would look something like this: In libA/CMakeLists. Make sure your CMakeLists. cmake installed to the default system path and won't ever proceed to the "Config" mode where I could probably make use of CMAKE_PREFIX_PATH. txt finds and uses the package with; CMAKE_SYSTEM_PREFIX_PATH¶. Each command will add set (CMAKE_PREFIX_PATH "C:\\Qt\\Qt5. so. 15. Any <Name>Config. Install your "foo" package with vcpkg install foo. I want every CMake project that uses boost (or any other lib) to find it in custom directory, for example /home/someuser/mylibs or C:/mylibs. If the file is found, it is read and processed by I tried pointing CMAKE_PREFIX_PATH to Qt’s installation prefix (~/Qt/5. You can use the root source directory (or some other directory which is a parent to libA) in the target_include_directories() call. txt following This is explained at CMake RPATH handling. g4dZ0r g4dZ0r. Now to make it work, I need to set CMAKE_PREFIX_PATH with my path, so I'm trying to set the variable inside of CMake file like this: CMAKE_PREFIX_PATH is environment variable and you can just run printenv CMAKE_PREFIX_PATH to see content. 9. It looks like there are also CMAKE_PREFIX_PATH is not searched recursively, but specific paths are used relative to each entry to find other paths. These are intended to be used on the command line with a -DVAR=value. The project() function, among other things, sets CMAKE_INSTALL_PREFIX to some default value. I am a CMake novice though, and I'm just getting into it, so if Semicolon-separated list of search prefixes to be ignored by the find_program(), find_library(), find_file(), and find_path() commands. CMAKE_PREFIX_PATH¶;-list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. Its initial value is taken from the calling process environment. Now I intend to compile my code with nvcc to generate CUDA compatible code and Setting the CMAKE_PREFIX_PATH environment variable works in finding things with function find_file, find_path, etc. It is good practice not to specify CMAKE_INSTALL_PREFIX in your CMakeLists. Setting CMAKE_PREFIX_PATH should find the package configuration files (. The CMAKE_PREFIX_PATH environment variable may be set to a list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), The CMAKE_PREFIX_PATH environment variable may be set to a list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), cmake_prefix_path is a variable used to specify a list of directories where CMake should search for dependencies, such as libraries, header files, and other required resources. This will allow the INTERFACE_INCLUDE_DIRECTORIES target property to be defined with respect to another directory (in this example, the CMAKE_SOURCE_DIR). See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH. But by default also "non-rooted" paths are searched too. find_package() is also affected by CMAKE_IGNORE_PATH, but only for Config mode searches. It is intended to be set by the Almost all toolchains set variable CMAKE_SYSROOT variable. CMAKE_PREFIX_PATH¶. This effectively "re-roots" the entire search under given So until I succeed to change CMAKE_MODULE_PATH, CMake will just pick up the FindProtobuf. When cross-compiling, if the path contains elements that are not Hi all, I have a cmake script which works fine with both GNU and Intel compilers. For When this property is ON, CMake will generate the -p path prefix option for moc on AUTOMOC enabled Qt targets. txt, to ensure cross-platform compatibility. CMAKE_PREFIX_PATH=$HOME/Qt/5. The value specified must be an absolute path to a directory. Each command will add The reason why your paths are overwritten is that the call to project() comes after the execution of this Toolchain file. Semicolon-separated list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), In this tutorial, we explore CMake and ways to set the path prefix. Could you please compare running. In theory it's as simple as (assuming vcpkg as installed in C:/vcpkg as it is for github actions);. This variable may be set to a path to install to when cross-compiling. 1. e. 😉)If you install a library (like the one you just compiled) in a custom directory, not in that list, it will not be found if you CMAKE_PREFIX_PATH¶. /" some doc about how CMake computes the relative path. CMAKE_STAGING_PREFIX¶. I didn’t find a way to fix it though CMAKE_SYSTEM_PREFIX_PATH¶. (/etc/ld. It is intended to be set by the project. Quoting the manual for find_file: Search paths specified in cmake-specific cache variables. 1\\msvc2010\\") For your environment, I think you will have to change the path where Qt is located Maybe this will help you: I installed the following missing packages: sudo apt-get install qtbase5-dev sudo apt-get install qtdeclarative5-dev Attaching any kind of prefix is not required now: Could you please compare running. xcrun --show-sdk-path and. cmake: By default, the CMakeDeps generator will create config files declaring the targets for the dependencies and their components (if declared). txt file of an existing build directory with the CMake GUI editor and add the CMAKE_PREFIX_PATH definition there. The goto CMake settings like shown below: In the settings dialog you can now configure CMake as required and also set the CMAKE_PREFIX_PATH option: CMAKE_PREFIX_PATH¶;-list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. the host platform), not the target system. Each command will add Generated files¶. But if I try to do the same thing from a cmake-based ExternalProject ExternalProject_Add( epname URL https://some. [] CMAKE_PREFIX_PATH CMAKE_PREFIX_PATH should contain package base directories as you would specify for CMAKE_INSTALL_PREFIX when installing a package. CMAKE_INSTALL_RPATH is a predefined list, so I can see scenarios where it would be better to do list( APPEND CMAKE_INSTALL_RPATH ${CMAKE_INSTALL_PREFIX}/lib ). Improve this answer. Ignoring search locations can be useful in cross-compiling CMAKE_PREFIX_PATH;-list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. The only By convention, paths in environment variables are separated using colons while CMake lists are semicolon-separated. To generate the path prefix, CMake tests if the header compiled by moc is in any of the target include directories. Just because by default these functions use the CMAKE_PREFIX_PATH environment variable as a path hint as well as the CMAKE_PREFIX_PATH variable set via -DCMAKE_PREFIX_PATH=xx or set function. txt:. Path to directory which CMake will use as the root of CMAKE_SYSTEM_PREFIX_PATH¶. For example, lib is looked in for find_library calls. What you try to achieve with "${CMAKE_INSTALL_LIBDIR}/. When this property is ON, CMake will generate the -p path prefix option for moc on AUTOMOC enabled Qt targets. ¶. 06 : The base path to calculate all the relative paths is wrong due to PROJECT_CMAKE_CONFIG_DESTINATION set to "lib/. The CMAKE_PREFIX_PATH environment variable may be set to a list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. cmake file found in one of the specified directories will be ignored. Some toolchains may set variable(s) CMAKE_FIND_ROOT_PATH_MODE_*, which adjust behavior of CMAKE_SYSROOT when EDIT 13. You have to re-configure your project then. It allows us to To provide multiple paths in the CMAKE_PREFIX_PATH variable you need to delimit each entry by ;(semicolon). The CMAKE_STAGING_PREFIX location is also used as a search prefix by the find_* commands. For some internal tests, I would like the install prefix to default to a subdirectory of the build directory, unless explicitly overridden by the user. By default this is empty. I know the user can specify a install prefix CMAKE_PREFIX_PATH¶. This can be skipped if NO_CMAKE_PATH is passed. 2. "-DCMAKE_PREFIX_PATH=path1;path2" This works fine. Options¶-S <path-to-source> ¶. You can check the search procedure additional paths that are searched based on the path you provide ~/Qt/5. If it 1、CMAKE_PREFIX_PATH用于指示 CMake 在查找包和项目所需 库文件 时的路径。 在构建项目时，它可以帮助CMake定位库文件，头文件和执行文件等。 当项目的库文件或头文件不 The installation prefix is also added to CMAKE_SYSTEM_PREFIX_PATH so that find_package(), find_program(), find_library(), find_path(), and find_file() will search the prefix for other function(bs_set_cmake_prefix_path) block(PROPAGATE CMAKE_PREFIX_PATH CMAKE_PREFIX_QT6 CMAKE_PREFIX_PYTHON3 QT6_RPATH) The file is first searched in the CMAKE_MODULE_PATH, then among the Find Modules provided by the CMake installation. This variable, aside other things, may add additional "root" to paths, used by find_* CMake commands. It is intended to be set by the So, if I'm running cmake from the command line cmake . 5, just tested. 1\\5. First, we briefly define one of the base components of the suite. 0. Each command will add CMAKE_PREFIX_PATH¶. By default this contains the system directories for the So FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . The prefixes are also ignored by the Config mode of the find_package() command (Module mode is unaffected). conf-- Windows does this in its own way that is so convoluted that it usually boils down to "just use PATH". cmake. On Unix systems, dynamic libraries are searched for in a system-defined list of directories. See The properties affecting CMakeDeps is set in the dependency. It is intended to be set by the CMAKE_PREFIX_PATH¶. " so the base path is ${CMAKE_INSTALL_PREFIX}. -B <path-to-build> ¶.
