openCL using MFC

I want to use openCL in MFC.
But I encounter error. The error is that.

"1>OpenCL.obj : error LNK2019: _oclPrintDevInfo External symbol(Reference location: “public: void __thiscall OpenCL::GetDeviceInfo(struct _cl_device_id * *,char *)” (?GetDeviceInfo@OpenCL@@QAEXPAPAU_cl_device_id@@PAD@Z) function) don’t confirmation. "

I was accomplished to include the library file and header file. However the error is here…

I need using opencl with MFC.

Please help me.
