Compire opencl failed

[nujabse]

I tried to compile the opencl version of Vampire using the latest develop branch. However, the compile failed, the error messages are:

g++ -std=c++0x -DCOMP='"GNU C++ Compiler"' -c -o obj/gpu/initialize.o -O3 -mtune=native -funroll-all-loops -fexpensive-optimizations -funroll-loops -I./hdr -I./src/qvoronoi -std=c++0x -std=c++11 -DOPENCL  src/gpu/initialize.cpp

I'm quite sure that the needed opencl headers are corrected installed, can you take a look at this?
