cmake fails when using MSVC generator, using this command:

cmake -G "Visual Studio 15 2017 Win64" -Thost=x64 -DLLVM_ENABLE_PROJECTS=clang
-DLLVM_BUILD_TESTS=ON -DCMAKE_COLOR_MAKEFILE=0 -DLLVM_ENABLE_ASSERTIONS=ON
-DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_C_COMPILER="c:/Program files
(x86)/Microsoft Visual
Studio/2017/Professional/VC/Tools/MSVC/14.16.27023/bin/HostX64/x64/cl.exe"
-DCMAKE_CXX_COMPILER="c:/Program files (x86)/Microsoft Visual
Studio/2017/Professional/VC/Tools/MSVC/14.16.27023/bin/HostX64/x64/cl.exe"
"d:/llorg_ws/llvm/llvm"


with this:
