My fault. I prepared first version of this patch to use with
TeXworks.pro (actually I tried just to compile vs Qt5 using TeXworks.pro
but compilation fails due to missing headers, so I prepared a patch).
Now I tried to compile texworks using cmake _without_ patch but with
DESIRED_QT_VERSION=5 and compilation finished successfully. So no need
for this patch.

I just used example in Qt5 documentation. As for the order, I think
translations provided by Linux distribution should be checked at first.

Again, my fault. I began with TeXworks.pro and after switching to CMake
didn't try to compile and run texworks. Now I tried and it works fine, I
mean that after start texworks shows interface on Russian.

I don't know where translations for Qt5 application should "live" but,
for example, translations of Qt5 GUI of transmission go into
/usr/share/qt5/translations according to rpm (
see here: http://rpm.pbone.net or

Is that means that all resource files, including translations are
"incorporated" into executable? IMHO, it is good for portable
application but a bit strange for Linux distribution package.
In summary, I think only search for qt translation in distribution is
needed, the rest is Ok. I made one patch, 'system-trans.patch' and
checked how it works with CMake build-configuration system: all is Ok.

Farewell we call to hearth and hall!
Though wind may blow and rain may fall,
We must away ere break of day
Far over wood and mountain tall.
To Rivendell, where Elves yet dwell
In glades beneath the misty fell,
Through moor and waste we ride in haste,
And whither then we cannot tell.
With foes ahead, behind us dread,
Beneath the sky shall be our bed,
Until at last our toil be passed,
Our journey done, our errand sped.
We must away! We must away!
We ride before the break of day!
-- J. R. R. Tolkien
