CMake: Allow no install + custom on-device prefix for desktop builds
Allow such a combination
- staging prefix (CMAKE_STAGING_PREFIX / -extprefix) set to the
qtbase build dir
- install prefix (CMAKE_INSTALL_PREFIX / -prefix / on-device prefix) set
to some custom location
even for non-cross builds.
An example would be
configure -prefix /usr \
-extprefix ~/qt/qtbase_build_dir
CMake will put the Qt libraries in the qtbase build dir, ninja install
will not be required, but ultimately in order to run applications,
the Qt libraries are expected to be in /usr.
Support for this scenario was originally added for cross-builds in
062318feb2d3b7598409c7e81e4459c2f4607764 , but not desktop builds.
Such a build is useful when you want to have install rpaths different
from where Qt is initially installed to (the staging prefix).
This case doesn't really happen often when targeting desktop
platforms, it's mostly used for cross-compilation (e.g yocto).
Being able to have the same setup with a desktop build is nevertheless
useful for faster iteration on build system issues in such a scenario.
Amends 062318feb2d3b7598409c7e81e4459c2f4607764
