New description:

 Actually when compiling and running a qt5 application I need to set up
 explicitly the environnement variable QT_QPA_PLATFORM_PLUGIN_PATH or the
 application would not start with the error:

 {{{
 Fatal: This application failed to start because it could not find or load
 the Qt platform plugin "cocoa"
 in "".
 }}}

 It is not clear if this is a qt5 installation problem or if this should be
 handled by the application.

 Thanks
