Another option would be to maintain the project version in the doxyfile and
have the build procedure read the version from the doxyfile.

Something like:

#!/usr/bin/env perl
while (<>)
{
    if (/PROJECT_NUMBER\s*=\s*(\d+)([.](\d+)([.](\d+)))/)
    {
        print "#define MAJOR_VERSION $1\n";
        print "#define MINOR_VERSION $3\n";
        print "#define TINY_VERSION $5\n";
    }
}

Then in your build/make script:

readversion <doxyfile >version.h
