Subject: [PATCH] [clang] cmake: resolve symlinks in ClangConfig.cmake
|
|
|
|
Ensure that symlinks such as /usr/lib/cmake/clang-X.Y (pointing to
|
|
/usr/lib/llvm-X.Y/lib/cmake/llvm) are resolved. This ensures that
|
|
CLANG_INSTALL_PREFIX ends up to be /usr/lib/llvm-X.Y instead of /usr.
|
|
|
|
Partially addresses PR37128
