[Openmp-commits] [PATCH] D24959: [cmake] Fix for a bug https://llvm.org/bugs/show_bug.cgi?id=30489 "Cannot build with -DLIBOMP_FORTRAN_MODULES=True"

[Jonathan Peyton via Openmp-commits]

jlpeyton added a comment.

I think this introduces a race during parallel builds where the `POST_BUILD` for the targets `libomp-mod` and `omp` both try to create the `LIBOMP_EXPORTS_CMN_DIR`.

To fix this, directories can be created during configuration time using file(MAKE_DIRECTORY ...).  That way, all these lines can be removed:

  COMMAND ${CMAKE_COMMAND} -E make_directory ...
