[MSVC] hardcode path in LLVMExports.cmake of clang+llvm-18.1.8-x86_64-pc-windows-msvc

[ACWhaleN]

When I coding under GCC(amd64, Windows11) by using the chooseMSVCCRT macro, diaguids.lib is implicitly imported. And because the L476 of LLVMExports.cmake in the lib\cmake\llvm folder uses an absolute path, my program fails to build.

lib\cmake\llvm\LLVMExports.cmake: L475~L477

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

(when I use ninja)

ninja: error: 'C:/Program Files (x86)/Microsoft Visual Studio/2019/Professional/DIA SDK/lib/amd64/diaguids.lib', needed by 'test/qcc.exe', missing and no known rule to make it.

In fact, I have never used Microsoft Visual Studio 2019 Professional.

The problem was solved when I switched to LLVM installed with pacman in msys2.

Thanks for the report; I’m going to close this one though since it’s a duplicate of #86250.
