If the project is already arranged to be compiled with decent automation,
I do not think you need any change to the workflow.

You would have a version.cc file with

	static char program_version[] = "My Program " VERSION_STRING;

in it, and teach the build procedure how to compile and link this file.
Something like:

    version.o: version.cc
    	$(CXX) -o $@ -DVERSION_STRING=\""$(git describe HEAD)"\" $?
