// This #include helper file can be used to #include OpenCL source files
// either as regular C++ source files to be compiled with a C++11 compiler
// (as normally done with regular #include) OR embedded as a c-strings to C++
// programs.
//
// The included OpenCL files must be enclosed within OCL_SOURCE_BEGIN and
// OCL_SOURCE_END)" tokens as follows and everything between the tokens
// (including comments) will be part of the c-string:
// my_source.cl:
//   OCL_SOURCE_BEGIN
//   // some comment
//   int foo(int x_, int y_) {return x_+y_;}
//   OCL_SOURCE_END)"
//
// Example to #include the OpenCL source file to C++ as a source file:
//   #define OCL_CPP_INCLUDE "my_source.cl"
//   #include "ocl_include.inc"
//
// Example to #include the OpenCL source file to C++ as a c-string:
//   const char *my_source_string=
//   #define OCL_CSTR_INCLUDE "my_source.cl"
//   #include "ocl_include.inc"
