Summary
This package is one of the packages that Lintian believes is a metapackage: a package that exists for the convenience of users or installers to install a set of related packages. Packages that are not themselves metapackages must not depend on metapackages, since this may prevent the user from removing portions of the package set they don't need.

TODO
qt4-default
Instead of Build-Depending on qt4-default, replace it with qtbase4-dev.
You need to export QT_SELECT=qt4 in debian/rules.
If you build it manually and if your build system is qmake, please invoke qmake with the -qt4 first argument. If you use CMake, it should be picked up without further changes.
qt5-default
Instead of Build-Depending on qt5-default, replace it with qtbase5-dev.
You need to export QT_SELECT=qt5 in debian/rules.
If you build it manually and if your build system is qmake, please invoke qmake with the -qt5 first argument. If you use CMake, it should be picked up without further changes.
