cmake include directory from current directory

CMAKECURRENTLISTDIR (since 2.8.3) this is the directory of the listfile currently being processed. home/lloyd/src/VegaFEM/cmake/test_include_mkl.cpp:1:10: fatal error: mkl_blas. Although the typical CMake idiom is to use findpackage() for finding and populating CMake variables ( INCLUDEDIRS, LIBRARIES) for third-party packages, what youre suggesting can also be achieved using the GLOB subcommand of file(). From the Wiki: CMAKECURRENTSOURCEDIR this is the directory where the currently processed CMakeLists.txt is located in. usr/bin/c++ -std=c++14 -o CMakeFiles/cmTC_fdefb.dir/test_include_ -c /home/lloyd/src/VegaFEM/cmake/test_include_mkl.cpp Make: Entering directory ‘/home/lloyd/src/VegaFEM/CIBuild/CMakeFiles/CMakeTmp’īuilding CXX object CMakeFiles/cmTC_fdefb.dir/test_include_ The QDir class provides access to directory structures and their contents.

The DIRECTORY argument specifies another directory from which to retrieve the property value instead of the current directory. The targetincludedirectories() command is a more granular alternative that allows you to specify the include path for a single target. I think youre mixing up two different paradigms here. This is fine for small projects, but it can become unwieldy as your project grows. When run in cmake -P script mode, CMake sets the variables CMAKEBINARYDIR, CMAKESOURCEDIR, CMAKECURRENTBINARYDIR and CMAKECURRENTSOURCEDIR to the current working directory. Note that it doesn't have to be in order - you can target_link_libraries on targets before they are defined.I am trying to figure out during configure time if the BLAS I find (ubuntu-20.04) is from Intel MKL, or some other vendor. The includedirectories() command adds the specified directories to the include path of all targets in the current directory scope. overall, I do not think every project inside system wants to compile his own separate instance of corelib, rather one corelib should be shared. Relative paths are treated as relative to the current source directory. The DIRECTORY argument specifies another directory from which to retrieve the property value instead of the current directory.

Project(collections VERSION 0.1.0 LANGUAGES C)Īdd_subdirectory(./private/corelib $/bin' Stores a property of directory scope in the named .

Trying to resolve said dependency, I have come up with the following CMakeLists.txt in 'collections': cmake_minimum_required(VERSION 3.0.0) I have a dependency of library 'corelib' in library 'collections'. The plan is to link the libraries in such a way that, during development, no manual recompilation of 'corelib' should be required to receive updated code from it, while also ensuring that dependencies would be resolved once all libraries get compiled as SHARED libraries and put in a place such as 'usr/local/lib' or similar. The main program uses one library, and each library uses the other one. In addition: I am not sure why you would want to exclude a single file. cpp when I include something from the local include folder it works, but not for the something that is in a different folder. look at the documentation for the '-I' option of GCC 4.6. So I want to include a global header file that is in a different folder.

It simply passes those directories directly to the compiler as a search-dir for your 'include <.>' E.g.

Įvery directory including 'bin' sub-directories is a separate library. In terms of CMake, you only need one CMakeLists.txt file at the top, which will just build one program and list every cpp file in every sub-directory, like this: addexecutable(main. An includedirectories call in CMakeLists does not result in a list of all available header-files. CMAKECURRENTSOURCEDIR) and converted to an absolute path before storing it in the associated target property. A relative path will be interpreted as relative to the current source directory (i.e. The project consists of the following directory structure (as of now). Specified include directories may be absolute paths or relative paths. I am working on a C project as of recently and want to learn how to use CMake properly. You can think about setting CMAKEUSERELATIVEPATHS to ON which will convert the include paths back during generation of the build environment to paths relative to your CMAKEBINARYDIR directory (but it works only with the Makefile generators).
