LLVM's cmake standard explicitly lists all source in the CMakeLists.txt. Remove globbing for source files in OpenMP's CMakeLists.txt. Also see #4899, #71404, https://reviews.llvm.org/D79906, https://reviews.llvm.org/D31363, https://reviews.llvm.org/D61275, https://discourse.llvm.org/t/cmake-builds-clang/11536, and CMake's note at https://cmake.org/cmake/help/latest/command/file.html#glob. Two reasons to not glob for source files is that it breaks bisecting and incremental builds. Renaming a file, reverting or checking out an older reversion where a newly added source file disappears again will not trigger a CMake configure step and make the build fail because of a non-existing source file.
