Comment (by michaelld@…):

 Replying to [comment:11 nietzsche@…]:
 > The problem here is when using cmake outside of the scope of MacPorts so
 I suggest a fix for the 'FindQt4.cmake'-module.

 When using cmake outside of MP, just set the environment variable QMAKE to
 the correct location -before- doing find_package(qt4 ...). Should be good
 to go. That's what we do inside MP for all practical purposes & it works
 nicely. Yes, it's true that this is a slight inconvenience; but, it allows
 for each parallel install of qt4 and qt5, which is desirable.
