 The first question is why the compiler id check fails:

> -- The CXX compiler identification is unknown

The log files listed at the end of the output may have more details:

 Hi, I've uploaded files. Sorry, didn't pay attention on:

 Thanks. CMakeError.log reports failure to identify the C++ compiler with:

 g++.exe: error: CreateProcess: No such file or directory

Try this:

 $ touch empty.cxx
 $ g++ empty.cxx

 I've received following output:

g++.exe error: CreateProcess: No such file or directory

 Seems, that this is MinGw g++ bug?!

 Yes, it seems CMake is correctly reporting that g++ is not able to build a simple test program.

 Hi,

I've just finished conversation on MinGw bug tracker, and faced that g++ should'n build and link empty file into executable, because there is no main entry point in empty source. I even don't understand how I did'n think about this by myself... But it doesn't matter.

Are you sure that g++ should build executable from empty file?

May be this is CMake's bug though?

 Create a "main.cpp" file containing "int main() { return 0; }" and try compiling that with g++.

 Yes, you are right. Build failed with the same symptoms.
