<div dir="ltr">The cache does *not* reveal what's actually used to generate, it reveals what was last cached. What is actually used to generate is whatever the logic in your CMakeLists files dictates. In your case, you should end up with "/MT" everywhere that you want to and it should work. (Verify it by looking at the settings in Visual Studio, or by doing a make VERBOSE=1 and inspecting the actual flags used to compile.)<div>

<br>My CMakeLists.txt is simple, with one directory, one lib, and one executable.

<br>These seem to only affect the *_INIT vars, because after running cmake inspecting the cache reveals:<br><br>> grep ^CMAKE_CX*_FLAGS CMakeCache.txt'<br><br>CMAKE_CXX_FLAGS:STRING= /DWIN32 /D_WINDOWS /W3 /Zm1000 /EHsc /GR<br>
