[CMake] How to Switch to Static Runtime on Command Line?

[Eric Doenges]

I think it is worth adding to what Mateusz wrote that the 
MSVC_RUNTIME_LIBRARY property / CMAKE_MSVC_RUNTIME_LIBRARY variable are 
only available if policy CMP0091 is set to NEW, which it will not be 
because LLVM's CMakeLists.txt only requires CMake 3.4.3 or later (and 
thus all policies introduced after 3.4.3 are set to OLD for 
compatibility). So if you do not want to edit LLVM's CMakeLists.txt, you 
need to use the options provided by LLVM's CMake project to control the 
build.

We select the CRT LLVM's libraries will use with the LLVM_USE_CRT_DEBUG 
and LLVM_USE_CRT_RELEASE options, i.e. to build with a static MSVC 
runtime we use

-DLLVM_USE_CRT_DEBUG=MTd -DLLVM_USE_CRT_RELEASE=MT

These options are not documented on the "Building LLVM with CMake" page, 
but can be found by looking into LLVM's cmake directory.
