Issue

Hi, I am a developer for Apache Arrow. Our windows CI has been failing recently. Error message is:

(arrow) C:\projects\arrow\cpp\build>cmake --build . --target install --config Release   || exit /B 
ninja: error: 'C:/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/DIA SDK/lib/amd64/diaguids.lib', needed by 'release/gandiva.dll', missing and no known rule to make it

Our ci environment has VS2019 community version but ninja is looking for the enterprise version.

After some digging I found out there's a portability issue with Conda's packaging of LLVM on windows.

LLVM's target LLVMDebugInfoPDB has a dependency on this file "${LIBPDB_LINK_FOLDERS}diaguids.lib" (https://github.com/llvm/llvm-project/blob/main/llvm/lib/DebugInfo/PDB/CMakeLists.txt#L17).

I downloaded Conda's llvmdev package win-64/llvmdev-15.0.1-h0f93eaf_0.tar.bz2 for windows from: https://anaconda.org/conda-forge/llvmdev/files

In the file Library/lib/cmake/LLVMExports.cmake line 410, it writes:

set_target_properties(LLVMDebugInfoPDB PROPERTIES  INTERFACE_LINK_LIBRARIES "C:/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/DIA SDK/lib/amd64/diaguids.lib;LLVMBinaryFormat;LLVMObject;LLVMSupport;LLVMDebugInfoCodeView;LLVMDebugInfoMSF") 

The full path is specified instead of using CMake vars. Apparently it is packaged on a platform with VS2019 Enterprise installed.
