Rpath

[efa]

With this patch now RPATH is set to executable path: $ chrpath -l airspaceconverter airspaceconverter: RUNPATH=$ORIGIN This should solve: https://github.com/alus-it/AirspaceConverter/issues/119

Has to be fixed for 'airspaceconverter-gui' too

[efa]

I tryed to manually add '-Wl,-rpath,$$ORIGIN' to LIB line of 'buildQt/Makefile' and work, 'airspaceconverter-gui' can find .so it its executable path and not only in CWD.

But I do not know the syntax to fix 'AirspaceConverterQt/AirspaceConverterQt.pro', adding '-Wl,-rpath,$$ORIGIN' to 'unix: LIBS' line does not generate a right Makefile

[efa]

found a way, adding the line with escaped ' and $: unix: LIBS += -L$$PWD/../Release/ -lairspaceconverter \'-Wl,-rpath=\$$ORIGIN\' in AirspaceConverterQt/AirspaceConverterQt.pro generate the right Makefile and the binary has the right RPATH:

$ chrpath -l airspaceconverter-gui
airspaceconverter-gui: RUNPATH=$ORIGIN

now it can find the .so

I will do another pull request after this one is in

[efa]

I noticed now that with this pull request on RPATH branch, it is included the pull request on master branch about space trim reading Cup files. Will try to fix this

[efa]

This happened because I created the RPATH branch after the pull of space trim on master branch in my repo. I deleted the RPATH branch, I think I had to wait the space trim pull be included in upstream repo, and then re-create the branch and re-create this pull request for RPATH
