This is correct way during installation.
Paths added to files in /etc/ld.so.conf.d/ locate libraries you consider
as installed, means permanent locations.
So, if  /home/myusername/src/qgis/Quantum-GIS/build/lib is
such permanent location, but not only location of building, debugging
and testing, then it is OK to add it to /etc/ld.so.conf.d/qgis.conf

But, if the location above is for testing and debugging only,
then I'd suggest to set it with LD_LIBRARY_PATH for the current
environment session. So, the setting is not permanent.

Read section 3.2 and 3.3 where you have it explained:
