Yes, i have some stuff that doesnt quite need to be there, but it doesnt hurt. I removed all possible linkings and made them "hardcoded". If i add blackflycam.cpp to the sources, therefore it is compiled, i get those errors. If i dont, all runs smooth. The thing is, the code that i replaced with that file, has the exact same includes and non of them are qt-related, so i dont know what the hell is going on here !
Now I use $$PWD/../3rdparty/assimp-3.1.1/include(2x '$') for all platforms, including Android, but I still can't build my .pro for it. For using $PWD I should set it to the right value in Projects->Build Environment, for each kit separately, right?
