Log:
CMake: Report an error if there is an unknown .cpp file in a source
directory.

This is useful in case someone who works with the config&make build
system forgot to add a file to its CMakeLists.txt. Instead of
obtaining undefined references at link time, cmake will complain at
configure time on the first build after a svn update.
