Creating device context in OpenCL for embedded profile

I am able to create context and devices in OpenCL by doing

     using namespace cl;
     std::vector<Platform> platforms;
     Platform::get(&platforms);
     cl_context_properties properties[] = 
                        {CL_PLATFORM_NAME,
                      (cl_context_properties) (platforms.at(0))(),0};
            context = Context(CL_DEVICE_TYPE_ALL, properties);
            devices = context.getInfo<CL_CONTEXT_DEVICES>();

It is working well with CPU and GPU devices. If I try the same for FPGA devices I get error in method clCreateContextFromType(). The context constructor is wrapping this method.

How should I create context and devices for OpenCL devices such as FPGA with embedded profile.

FPGA devices usually require to link additional vendor specific OpenCL driver libraries. What are the libraries to link with is usually specified in the vendor documentation and/or examples.

For Altera that can be found in their documentation: 1.7.6 Managing Host Application

For Xilinx in their examples (by OP): github.com/Xilinx/SDAccel_Examples
