Thank you very much for looking into it!

I am also digging on my side. It seems to me that the problems come from
${vtk-module}_EXPORT_CODE_INSTALL which is not exported into corresponding
installed ${vtk-module} cmake file. Normally this cmake variable should
contain

"find_package( Qt5Widgets QUIET)" given the path corresponding dir. But it
seems it is not present in the install tree for all module dependent on
Qt5...
