Of course, you do the same thing if you want to make sure that gdb from
/usr/local is used instead of the one from /usr/bin.

I don't see a hack.

Can you please elaborate, I have no idea what a/b or foo/bar refer to in
this example. However qmake knows exactly where the headers and libs
(and data) for the Qt its supposed to be used with are. So having the
right qmake first in your PATH is the right thing to setup. Either that
or look into the docs for FindQt4.cmake to find out the name for the
CMake variable that the module accepts for pointing to the right qmake
binary.
