@cyrilf , yes you need to source the environnement to avoid the error with cmake. Did you configure your mobile device (in qtcreator) to deploy directly on the card ? Like Graugans describe here ? In this way you didn't need to use scp (i never use it, i do all my deploy with qtcreator). I suppose you are using udooquad for your test, can you check that the module galcore is loaded with lsmod in your card ? In my case i never have this issue for the moment (is the card boot on lvds7 or hdmi ?) !
