[solved]: superbuild on macOS: only sytem qt5

trying to build superbuild on macOS 10.15 (Catalina) ENABLE_qt5 fails as it cannot find it on the system. It works with -DQt5_DIR=/usr/local/Cellar/qt/5.15.0/lib/cmake/Qt5/ with a qt installed via brew.

So there is no easy way to include qt5 in a own build?

The question is more out of curiosity than real need (that stuff comes soon :)).

I meanwhile understood that using the system qt5 seems to be the preferred way. So the question can be closed
