[SailfishDevel] Qt5SystemInfo status

I've had a similar issue: I needed Qt SystemInfo to integrate analytics 
into my app.

The recommended way to solve linking against non-whitelisted libraries, 
is to ship them together with your app. However, just taking 
libQt5SystemInfo.so.5 from Sailfish repos and putting it into your RPM 
won't work: it links against other non-whitelisted libraries (namely, 
SSU, and SSU links further). So my solution was to build a custom 
version of libQt5SystemInfo.so.5, which excludes non-whitelisted libs.

The source for Sailfish version of Qt SystemInfo is available here:

I don't remember the qmake flags exactly (I can check them when I'm back 
home, if you need), but I think they were:
 > qmake CONFIG+=ofono CONFIG+=nox11option

This will produce Harbour-compatible version of libQt5SystemInfo.so.5 
which you can link against and include into you RPM.

Or, you can reuse my version of it. It's available here:

libQt5SystemInfo.so.5 is in rpm/lib/<arch> folder. You can take a look 
at taot.pro (lines 263-264, 278, and 284), rpm/harbour-taot.yaml (line 
44), and rpm/harbour-taot.spec to see how I include the lib into RPM.
