llvm built from master on gentoo is checked out using git instead of svn (the reason might also be that LLVM project is in the process of moving to git completely [1]). Because of that the llvm-config returns something like this: $ llvm-config --version 10.0.0git A year ago a patch [2] added support for the svn suffix, it would be nice to have support for the git suffix as well. Right now instead the llvm is not detected correctly: -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so -- Found LLVM (version: 10.0.0git): (using /usr/lib/llvm/10/bin/llvm-config) -- Include dirs: /usr/lib64/llvm/10/include -- LLVM libraries: /usr/lib64/llvm/10/lib64/libLLVM-10git.so CMake Error at cmake/modules/FindClang.cmake:116 (message): Could not find Clang builtin directory Call Stack (most recent call first): plugins/CMakeLists.txt:43 (find_package) [1] http://blog.llvm.org/2019/08/the-llvm-project-is-moving-to-github.html [2] https://phabricator.kde.org/D15998
