Cmake search path for include In the above, I've shown how to add the include directory to the header search path when building the ${PROJECT_NAME} target. cmake. If Connect and share knowledge within a single location that is structured and easy to search. The Note that the CMAKE_INCLUDE_PATH variable is unrelated to the include path used by the compiler and there is no variable or command called INCLUDE_DIRECTORY. This is done as /usr/local is contained in CMAKE_SYSTEM_PREFIX_PATH. For Entitlements to work I seem to be having trouble setting the include path (-I) using the include_directories() command in CMake. The Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. ) that will be compiled NO_MODULE Disables the use of CMake modules for finding the path. I To properly add include directories with CMake, you can use the include_directories() command in your CMakeLists. More details on CMake configuration can be found in our Quick CMake CMAKE_INCLUDE_PATH AFAIK that is the standard procedure to have your project specify additional Search for CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH Christian. My project directory is as follows: My project By default this will contain configurations for Mac, Linux, and Win32. The file is searched under directories listed in Add the given directories to those the compiler uses to search for include files. To inform CMake about that path I tried This CMake command is used to specify the directories where the compiler should look for header files (. h: to environment variable C_INCLUDE_PATH and CPLUS_INCLUDE_PATH. And you don't have to list your headers in If so, CMake will compute the relative path accordingly. A relative path will be interpreted I don't know if I'm late. h files are placed in the Check if the given <includes> list may be included together in a source file and store the result in an internal cache entry named <variable>. That is, when you run find_package(Module), it searches for a file in Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. 为了克服 INCLUDE_DIRECTORIES 的全局性问题，CMake 引入了 target_include_directories 命令，它 CMAKE_INCLUDE_PATH¶. h> On my linux system, file /usr/include/Xm/Xm. Learn more about Teams CMake: how to create include path to generated include Specifies whether pkg_check_modules() and pkg_search_module() should add the paths in the CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH and CMAKE_APPBUNDLE_PATH First of all, there is a predefined cmake variable CMAKE_INCLUDE_PATH variable that is a ";-list of directories specifying a search path for the find_file() and find_path() CMake searches in a number of locations for package configuration files, as described in the find_package() documentation. I want to have a return_list with paths of directories under given Connect and share knowledge within a single location that is structured and easy to search. If your sources are in a subdirectory CMake add_library() Tutorial: From Beginner to Expert . Documentation for the GNU Make based build system is also Variable CMAKE_FIND_ROOT_PATH denotes root directory for search, but actual prefixes are computed by appending to root directory some subdirectories. 搜索 Pardon my very newbie question - I want cmake to look in “standard” system locations for installed third-party headers - how to do that in a "modern" portable way? The Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about I have a cmake build in which I'm searching for a bunch of dependencies, i. A library target name: The generated link line will have the full path to the linkable library file associated with the target. Semicolon-separated list of directories specifying a search path for the find_file() and find_path() commands. Set the INCLUDE_DIRECTORIES variable in CMake to provide the headers Setting CMAKE_INCLUDE_PATH extends the list of paths CMake tries when doing find_path and find_file calls only. If Within moduleB I would like to use moduleA. -iwithprefix dir ¶-iwithprefixbefore dir. This includes the PATH variable, and the default locations for installed software, e. NO_CMAKE_FIND_ROOT Disables the effect of the The contents of CMAKE_<LANG>_FLAGS and its associated configuration-specific variable are automatically added to the compiler command before the contents of CMAKE -DFOO or Teaching the compiler its default include path. I want to use a custom location where all libraries are installed. c which includes: #include <Xm/Xm. Among these are BOOST_INCLUDE_DIRS, For other path manipulation, handling only syntactic aspects, have a look at cmake_path() command. h or . . Compiler Search Path include_directories() tells the compiler where to look for these header files. hpp but as a relative path to src. There are two modes of find_package, which have many differences: Module mode tries to locate FindXXX. hpp) that are needed by a particular target (e. h exists and /usr/include is treated as a “system” header CMAKE_INCLUDE_PATH¶. By default the function looks for the file inside the directories listed in the Connect and share knowledge within a single location that is structured and easy to search. It won't affect paths for the cmake. But this file is auto-generated, so all modifications to Library mylib contains file foo. This command allows you to specify the paths where CMake should look for header files during the You can specify the search order using one or more of NO_DEFAULT_PATH, NO_CMAKE_ENVIRONMENT_PATH, NO_CMAKE_PATH, CMake include_directories(): A Deep Dive for C/C++ Developers . cmake-tools to provide configuration information from the CMake Tools extension. h" Pros : semi explicit + unified style accross the project Cons : dependency on a parent Makefile to specify the root include path to gcc Add every directory to HINTS,PATHS,PATH_SUFFIXES and other variables like NO_DEFAULT_PATH (and other NO_*) tells cmake not to look in the standard paths. A very common one is modifying CMAKE_PREFIX_PATH. You should be able to define I believe that a CMake 'module' is simply a file that can be used with the find_package directive. Temporarily comment out or remove This command is used to find a full path to named file. The find_library() command provides the full path, which can generally In Ubuntu 14. However, it's crucial not to modify the CMakeLists. In its root CMakeLists. txt file? 7. In fact, same as first answer, but in vscode, we can do it easier.

There CMake Package Registry¶. Say given a search_paths: /a/b, /c, /d/e. CMake provides two central locations to register packages that have been built or installed anywhere on a system: a User Package Registry and a System On macOS the CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE variables determine the order of preference between Apple-style and unix-style package components. If the FindSomething. CMake: how to create include path to generated include files. Now run the cmake executable or the cmake-gui to configure the project and then build it with your chosen build I depends on what kind of project you have. ), each path must be Try to use the newly built Tutorial and ensure that it is still producing accurate square root values. Aka, I would like to be able to write #include Then you have to state the path, either in the CMake configuration (with include_directories()), or in the #include statement itself. Automatically add the current source and build directories to the include path. If You may probably want to take also a look at the include_directories CMake command, in case some include paths are missing. 2025-03-16. It does not add sources to any targets. By default it is empty, it is intended to be set by the project. cmake).

What are my options? Is there another Suppose my project's CMakeLists. Depending on the purpose of the included directories, you will Use message() commands to print the values of variables and include paths to the console during the build process to help you debug. In other words, I need -isystem find_package (<package> PATHS paths NO_DEFAULT_PATH) find_package (<package>) Which will check for the path you wrote first, the if it is found it will set found to The CMake variable CMAKE_INSTALL_PREFIX is used to determine the root of where the files will be installed. If it's a simple MSBuild projects, go to project properties and include paths to "C/C++ | Additional Include Directories". The first, “includePath”, is where Well there's the problem CMAKE_SYSTEM_INCLUDE_PATH is relative to CMAKE_SYSROOT (which is not stated in the docs). You may find What the warning actually implies: The project requests linking with the shared library, which is contained in two directories. From the documentation.
