[Bug 1624832] [NEW] AUTORCC-generated resources always out-of-date with Ninja

[Elvis Stansvik]

Public bug reported:

When using AUTORCC with the Ninja generator, the generated qrc_*.cpp.o
target is always considered out-of-date, leading to an unnecessary (and
possibly lengthy) re-link on each build. This defeats one of the main
strengths of Ninja, which is its fast no-op build time.

The upstream bug report is here:

    https://cmake.org/Bug/view.php?id=16049

and was later moved to here:

    https://gitlab.kitware.com/cmake/cmake/issues/16049

It was fixed by Brad King in

https://gitlab.kitware.com/ben.boeckel/cmake/commit/f6c5958047ee8a9084bf230a6c1acb4801cb2b93

and the fix is in CMake 3.5.2.

I would like to ask what is best: Should I should prepare a debdiff
adding this patch to the 3.5.1 package in Xenial and request an SRU? Or
is it reasonable to update the Xenial package to 3.5.2 (which is in
Yakkety) outright?
