Revert "Determine up front which projects are enabled."

This was intended to be a generic CMake solution to a problem
shared across several projects.  It turns out it doesn't interact
very well certain CMake configurations, and furthermore the
"problem" is actually not a problem, as the problematic code
is never executed to begin with.  So this really isn't solving
anything.
