[Qgis-developer] error starting qgis (built from source)

[Yves Jacolin]

That's great!

Yes "cmake ." command allows you to setup the location where qgis (bin, and 
lib) will be located. Related to this settings you should adapt it for 
ld.so.conf.d  config file.

For me, I install qgis in /usr/local/ which is the default one, in another 
computer I created other location because I have several release of qgis for 
different task (working, testing and trainings) so I have to adapt each time 
the ld.so.conf.d file :)
