[CMake] Error because of MSVC_RUNTIME_LIBRARY value

[Денис Смирнов]

*Here is my root CMakeLists.txt file:*
cmake_minimum_required(VERSION 3.15)

cmake_policy(SET CMP0091 NEW)
project(test_masm)

set(CMAKE_MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>")

add_subdirectory(src)

*Here is the src/CMakeLists.txt file:*
enable_language(ASM_MASM)
add_executable(test_executable main.asm)

*src/main.asm is empty.*

After run cmake.exe I get error "*MSVC_RUNTIME_LIBRARY value
'MultiThreadedDebug' not known for this ASM_MASM compiler*".

*Here is the full listing:*
cmake.exe -G "Visual Studio 16 2019" -A x64 ..

Can someone please tell me if I am doing something wrong or it's a bug?
