vvereschaka added a comment. I tried to reproduce the problem on the builder in a temporary folder and I found that CMAKE_SOURCE_DIR == CMAKE_BINARY_DIR == <build_dir>. Here is a list of all CMAKE_ variables available on a moment of initial configuration:
-- CMAKE_AR: c:/buildbot/temp/build/bin/llvm-ar.exe -- CMAKE_BINARY_DIR: C:/buildbot/temp/build -- CMAKE_BUILD_TYPE: Release -- CMAKE_CL_SHOWINCLUDES_PREFIX: Note: including file: -- CMAKE_COMMAND: C:/Program Files/CMake/bin/cmake.exe -- CMAKE_CPACK_COMMAND: C:/Program Files/CMake/bin/cpack.exe -- CMAKE_CROSSCOMPILING: ON -- CMAKE_CTEST_COMMAND: C:/Program Files/CMake/bin/ctest.exe -- CMAKE_CURRENT_BINARY_DIR: C:/buildbot/temp/build -- CMAKE_CURRENT_LIST_DIR: C:/buildbot/temp/llvm-project/clang/cmake/caches -- CMAKE_CURRENT_LIST_FILE: C:/buildbot/temp/llvm-project/clang/cmake/caches/CrossWinToARMLinux.cmake -- CMAKE_CURRENT_SOURCE_DIR: C:/buildbot/temp/build -- CMAKE_CXX_FLAGS: -D__OPTIMIZE__ -- CMAKE_C_COMPILER_TARGET: armv7-linux-gnueabihf -- CMAKE_FILES_DIRECTORY: /CMakeFiles -- CMAKE_HOST_SYSTEM_NAME: Windows -- CMAKE_HOST_WIN32: 1 -- CMAKE_INSTALL_PREFIX: ../install -- CMAKE_MAJOR_VERSION: 3 -- CMAKE_MINOR_VERSION: 10 -- CMAKE_PATCH_VERSION: 2 -- CMAKE_ROOT: C:/Program Files/CMake/share/cmake-3.10 -- CMAKE_SOURCE_DIR: C:/buildbot/temp/build -- CMAKE_TWEAK_VERSION: 0 -- CMAKE_VERSION: 3.10.2 Looks like this is a feature (bug?_ of CMake. CMake doc says CMAKE_SOURCE_DIR The path to the top level of the source tree. This is the full path to the top level of the current CMake source tree. For an in-source build, this would be the same as CMAKE_BINARY_DIR. When run in -P script mode, CMake sets the variables CMAKE_BINARY_DIR, CMAKE_SOURCE_DIR, CMAKE_CURRENT_BINARY_DIR and CMAKE_CURRENT_SOURCE_DIR to the current working directory. `-C` could be some kind of the script mode. May be. We use CMake 3.10.2 on the builders. I think may be it is optimal to use `CMAKE_CURRENT_LIST_DIR` to calculate a direct path to required file. We always know where it is. Something like that get_filename_component(LIBCXX_CXX_ABI_INCLUDE_PATHS "${CMAKE_CURRENT_LIST_DIR}/../../../libcxxabi/include" ABSOLUTE CACHE) Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D74347/new/ https://reviews.llvm.org/D74347 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
