msys2, mingw64 compiling

Hello
kot prvo sem totalen noob kar se tiče tega compilanja v msys/mingw64.
Poizkušam zbuildat s pomočjo cmake nekaj pa dobim error

-- The CXX compiler identification is unknown
-- Check for working CXX compiler: C:/MinGW/bin/c++.exe
-- Check for working CXX compiler: C:/MinGW/bin/c++.exe -- broken
CMake Error at C:/msys64/mingw64/share/cmake-3.12/Modules/CMakeTestCXXCompiler.cmake:45 (message):
The C++ compiler

"C:/MinGW/bin/c++.exe"

is not able to compile a simple test program.

It fails with the following output:

Change Dir: D:/git/app/build/release/translations/CMakeFiles/CMakeTmp

Google ni nič pomagal ali bodo strici s slo-tech? :)

sec trying:)

c++.exe: error: D:/git/app/build/release/translations/CMakeFiles/CMakeTmp/testCXXCompiler.cxx: No such file or directory
c++.exe: fatal error: no input files
compilation terminated.

Saj, pri poskusu bolje opisat problem bo morebiti že našel tudi rešitev. ;)
