Ok, so I'd line to have the release options plus -pg on compilation and linking and name the option -DCMAKE_BUILD_TYPE=Profile. > > > > > 2.

Not really, but it makes Makefiles three times bigger than they need to be (not _really_ important) and the 'cd ...' part somehow does not look optimal either (not _really_ important either as long as the result is not slower than the automake Makefiles).
