Shouldn't qt5 also include cmake?

[René J.V. Bertin]

As a PS: something that might make sense is to provide the qmake portgroups with an "out_of_source" option like the cmake portgroup has. I'm not sure to what extent all qmake versions and qmake-based projects have sufficient support for that (QtWebengine doesn't support it, for instance), but sure helps during port development if one can restart a build by simply removing the build directory.
