[Beignet] fatal error: 'ocl.h' file not found

[Yuan, Shengquan]

I build latest beignet from git, and copy "libcl.so - libgbeinterp.so - libgbe.so  beignet.bc" into another Skylake Ubuntu desktop. clinfo or simple test program will report "fatal error: 'ocl.h' file not found".   Is there something wrong in my environment?
