My build log

Hi.

I am on Windows 10 x86_64(version 10.0.19041.508).
I am using CMake 3.19.
My CPU is Intel Q9400.

I have compressed my build folder - you can get the file here https://drive.google.com/file/d/1VHTF31TEF5PE81PoE4uQToAsIUYwyEV-/view?usp=sharing

The only way to get the warning message is to:
- be on Windows
- have neither MINGW nor MSVC be true

LLVM generally expects to be compiled in either one of these environments,
because it has to get the C library from somewhere, and that is typically
provided by either mingw or MSVC.

If you are using MSVC libraries and the Windows SDK, then you can switch to the
clang-cl driver and things will work. Use -DCMAKE_C_COMPILER=C:/Program
Files/LLVM/bin/clang-cl.exe.

While the gcc-style driver can be used in combination with the MSVC CRT, it is
difficult to use clang.exe with cmake, because there are many places where the
MSVC conditional is used to guard both 1. cl.exe-style compiler flags and 2.
things related to library support. Untangling the MSVC boolean into separate
flags for the command line flag syntax and the library environment would be
challenging.
