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.

In APPLE/patches/qt.cmake there is

> superbuild\_add\_project(qt5  
> MUST\_USE\_SYSTEM)

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
