[yocto] CMake issue - missing header files

[Martin Kiepfer]

Hi there,

I noticed a curious problem when trying to build a cmake based recipe.
During configuration phase pthead.h is found.

 cmake

But during build phase some header files can not be found?!

Also socket.h can not be found.
My receipe is very rudimentary:

Any idea how to resolve this?
Building the same application using Yocto Eclipse plugins works properly.
