Sorry for the delay. The test for MINGW must be in the else() branch, not as elseif() of MSVC. Just put the if(MINGW)/endif() in the else() branch.

Then I guess you can do if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU" AND MINGW), still within the else() branch.

looks like that's not related to this PR. maybe it's even a broken build...
