¿alguno sabe como solucionarlo?

[SingingBush]

the qtcam.pro file is Ubuntu specific although there's no reason for it to be. I've done some work toward unpicking it in #58 but there's still a little more to do. If #58 gets merged it may completely solve the build for Opensuse but may need a few more changes.
