Subject: [PATCH] [llvm] cmake: resolve symlinks in LLVMConfig.cmake
X-Git-Tag: archive/raspbian/1%9.0.1-10+rpi1^2~62
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=49c3438ef833b44dc7c8436b2276eda6190f3bf4;p=llvm-toolchain-9.git

[PATCH] [llvm] cmake: resolve symlinks in LLVMConfig.cmake

Ensure that symlinks such as /usr/lib/llvm-X.Y/cmake (pointing to
lib/cmake/llvm) are resolved. This ensures that LLVM_INSTALL_PREFIX
becomes /usr/lib/llvm-X.Y instead of /usr.

Partially addresses PR37128
