What were you trying to do?

I tried to recompile Natron in its build dir. Without Wayland.

What did you expect to happen? What happened instead?

Tried re-compilation (for some reason I still need to add " -lpthread -ldl -lc" to executable linker line in ccmake)

Step-by-step reproduction instructions

Try to build Natron on system without Wayland headers. Cmake detect they absent but some ifdefs are missing.
