[OSX] Ability to build LRC without the daemon
Issue generated from Tuleap's migration script. Originally submitted by: Alexandre Lision (alision)
This slows down our CI process since for OSX there is a static linking phase at the end of the LRC compilation.
We should be able to build LRC by only providing the daemon's headers.
This could be done by adding a cmake variable that disables the final linking step.
