Save Re-compile Time - Include moc Files in Source Files

Using CMake you most likely use AUTOMOC. This takes care of running moc on the files which need this.

It does, however, come with one drawback, namely that all moc files are compile together, which means that touching any header with a Q_OBJECT in it results in lots and lots of code being recompiled.

By including the moc files in the .cpp files I went from 22 seconds to 5 seconds when recompiling after touching a simple header file.

This episode comes with a script to automate this plus a git hook to ensure you always remember to include the moc files.
