[CMake] Mixing c and c++ with MinGW

[Werner Smekal]

Hi,

it is normally possible to mix c and c++ in a project with the GNU 
compiler. Normally you compile c files with gcc and c++ files with g++ 
and than link all together with g++.

In our project (plplot) we allow c++ code into the mainly c code library 
under some circumstances - everything works fine, ar links everything 
together.

We have now c and c++ examples which use this mixed library, but the c 
examples won't compile with gcc obviously since a lot of c++ stuff is 
unreferenced.

I tried to set CC to g++, but cmake didn't allow this.

Is there any solution for this problem?

Thanks,
Werner
