Cmake build issues

[Kyanoxia]

Expected Output

Following build commands should work smoothly and compile/build the project without error.

Real Output

When following directions listed in the README, I run the cmake command, as follows:

cmake -B build

and the build fails with this error:

CMake Error in /Users/$USER/Developer/opengd/axmol/core/CMakeLists.txt:
  The language OBJCXX was requested for compilation but was not enabled.  To
  enable a language it needs to be specified in a 'project' or
  'enable_language' command in the root CMakeLists.txt

As far as I can tell, Axmol is installed correctly (ran setup.py) and everything should work. Maybe should I clone the OpenGD repo inside the axmol folder?

OpenGD itself only builds on windows at the moment but this is an axmol issue. Not really sure since we don't use a mac. Maybe @halx99 can help

(use the no header optimization branch)

[halx99]

ONLY -GXcode supported.

cmake - B build -GXcode

no-header-optimization works properly only on GCC, I couldn't get it to work on Clang. Please ensure that you have changed the default compiler.

UPD: With commit ed299c8, OpenGD has been finally fixed on Linux.
