building qt submodules ?

[asmodehn]

Just a note that in my usecase I would have needed some of these as well : http://download.qt.io/official_releases/qt/5.12/5.12.9/submodules/

To be more precise, my cmake report some modules are not present...
Maybe this is a question of which cmake version is working properly with which Qt version...

[darkmattercoder]

Which of them exactly? Coukd you pass the cmake output?

What I do not include by default is qwebengine. Unfortunately that is simply because of I have not enough build time in the travis ci pipelines :-(

[asmodehn]

Yes it was the webengine... but I couldnt test more.

CMake's Find*.cmake modules might change significantly between releases... it is quite possible that some versions of cmake fail to detect all of Qt versions, where other versions will succeed... Probably something to add into the CI to make sure the installed cmake version finds everything...
Grabbing a more recent version to install on the image, when needed to detect recent Qt version, might be necessary.
