Do you expect the imports directory to exist before being able to
install something there? If not then this is not fixable since its not
possible anymore to decide wether the cross-compile stuff applies or the
qmake-variable should be taken (see the foreach right below your patched
line). If imports is supposed to at least exist, then one could simply
iterate manually over all possible locations and take the first one for
which file(EXISTS) returns true.

That being said, one could argue that a Qt installation without at least
Qt/widgets is broken wrt. QML, so maybe the packages containing the
standard Qt qml files should actually be a required dependency for the
declarative module.
