You’re doing it all wrong. You do not name source files as make targets, but
the target name (or project name, I have no idea, because it rarely makes sense
to name them differently). Try simply “foo” or “custom-command-target”. You
would never say “make foo.cpp”, not even in an ordinary GNU Make script.

In this example, how do I get
make foo.cc
to work?
