I wanted now to write some CMake code to ensure that Qt is always and
entirely linked dynamically. For that purpose, I intended to iterate
through the target properties LINK_LIBRARIES and
INTERFACE_LINK_LIBRARIES of Qt5::Widgets or Qt6::Widgets and check that
all dependencies resolve to shared libraries eventually.
I have now two questions. First, is there some existing code in the Qt
code base that does what I want already?
There is code for that as part of the .pri file generation, but it's not
ready to be used outside of its scope. See QtPriHelpers.cmake for details.
Secondly, I noticed that an interface dependency of Qt6::Widgets is
Qt6::CoreQt6::Gui and if I check whether Qt6::CoreQt6::Gui is a target
with "if (TARGET Qt::CoreQt6::Gui)", it turns out that it is not. This
confused me since it doesn't seem like a valid library name to me. How
can I resolve Qt6::CoreQt6::Gui to an absolute file path?
Qt6::CoreQt6::Gui looks wrong and should not appear as dependency.
Are you sure that this is not an artifact of your code that extracts the
dependencies?
Cheers,
Joerg
