CLion with NMake gives me C2220, C4530, U1077 errors

CMakeLists.txt (Part)

```
SET(CMAKE_CXX_FLAGS "/std:c++17 /permissive- /W4 /WX")
SET(CMAKE_VERBOSE_MAKEFILE TRUE)

I've written a simple C++ code and tried to build it with NMake(Visual Studio 2019) in CLion, but the compiler gives me above errors.

This error disappears if I remove `/WX`, but there was no issue like this when I use Visual Studio MSBuild project with same compile option.

How do I fix this with keeping `/WX` option?
