[CMake] RPATH for pkg-config

Fri Jan 5 03:14:45 EST 2018

Working !... At last ! Thanks :D 

I suspected an ordering problem: I already tried to change the position of "setting CMAKE_INSTALL_RPATH" before / after "calling target_link_libraries"... But didn't try to do this BEFORE add_executable ! 

Would be nice to add this in the doc https://cmake.org/Wiki/CMake_RPATH_handling : can somebody do that or should I post that to the dev-mail list ?!... 

Anyway, thanks guys
