[llvm-dev] Building LLVM with -DLLVM_TARGETS_TO_BUILD="X86" and Platform=Win32 with VS2019

[Michael Kruse via llvm-dev]

The platform for the Visual Studio project generated by cmake is called
"x64", not Win32 (assuming you compile for 64 bits). There is also just one
platform (AFAIK cmake does not support multiple per generated project), so
you can leave away the platform parameter.

This works for me:

cmake --build . --config Release
