CMake: how to get find_package to work with different versions of Qt?

[idlefrog]

I have a project that needs to support Qt4.8 and Qt5, and build with CMake.
In my CMake I have:

find_package(Qt5 COMPONENTS Core Gui Widget Xml REQUIRED)

But how do I generalise this so that it will work with either Qt4 or 5?
(Our build pipeline has one machine with Qt4 installed, and another with 5).

Hi,

You might be able to do something along the lines of the version less cmake targets used for Qt 5 and 6.

@SGaist Thank you! That might do the job. Will need to experiment with it.
