This is probably due to ocl-icd 2.2.8 adding CL/cl_egl.h to the headers #included by ocl_icd.h (https://anonscm.debian.org/cgit/collab-maint/ocl-icd.git/commit/icd_generator.rb?id=9fdd8caf362d9b848f6a722e05e4f79768a82f72).
The obvious (but untested) fix is to add a dependency on libegl1-mesa-dev, but does that belong in ocl-icd-dev or beignet?
It is likely that pocl (the other user of ocl-icd-dev in main) is also affected, but I haven't tested this.
