Using developer-build of Qt6

beroset

I'm trying to help test patches for this issue. I have downloaded and successfully build Qt6 from source after configuring with this command:

../qt5/configure -developer-build -opensource -nomake examples -nomake tests -confirm-license

However, now I can't figure out how to get my CMake-based test program to find that Qt6 version. Specifically, when I configure my project with -DCMAKE_PREFIX_PATH=~/tools/qt5-build/qtbase/lib/cmake/Qt6 it reports that it can't find either Qt6::DBus or Qt6::QML, both of which are required in my project. Also, I have no other version of Qt6 installed on my machine (a Linux box running the latest Fedora distro), but I do have Qt5 installed.

How do I fix this?

@beroset said in Using developer-build of Qt6:

-DCMAKE_PREFIX_PATH=~/tools/qt5-build/qtbase/lib/cmake/Qt6

Qt6DBus, Qt6Qml are directories in parallel to Qt6 directory. That is, pass e.g. -DCMAKE_PREFIX_PATH=~/tools/qt5-build/qtbase/lib/cmake, or just -DCMAKE_PREFIX_PATH=~/tools/qt5-build/qtbase

@kkoehne Thank you so much! Using -DCMAKE_PREFIX_PATH=~/tools/qt5-build/qtbase as you suggested works perfectly.
