The default glob options for define_source_files are a little odd, only looking for *.cpp and *.h files. The common file extensions should likely be:
Source Files glob: *.c *.c++ *.cxx *.cpp *.cc *.C
Header Files glob: *.h *.hh *.H *.h++ *.hxx *.hpp *.hcc
I have submitted a pull request to make that change (just a two line change). Is this acceptable or did I miss any?
