[Openmp-commits] [openmp] [openmp] Allow to build doxygen-openmp in the stand alone mode (PR #181723)

[Dmitry Vasilyev via Openmp-commits]

https://github.com/slydiman created https://github.com/llvm/llvm-project/pull/181723

doxygen-openmp can be built in 30 sec but it takes 30 min because of LLVM tools dependencies added by llvm-project/runtimes/CMakeLists.txt. Currently doxygen-openmp requires to build LLVM and clang. We can remove clang dependency adding `if (LLVM_INCLUDE_TESTS)` in 2 CMakeLists.txt files inside openmp but it will not remove LLVM tools dependency. After this patch we can use the stand alone mode to build doxygen-openmp in seconds.
