[Build] cannot convert ‘cl::Platform’ to ‘cl_platform_id’

[Sergei Zimmerman]

opencl/device_manager.cpp:265:52: error: cannot convert ‘cl::detail::param_traits<cl::detail::cl_device_info, 4145>::param_type’ {aka ‘cl::Platform’} to ‘cl_platform_id’ {aka ‘_cl_platform_id*’} in initialization

Description

This error is due to breaking change to opencl-clhpp https://github.com/KhronosGroup/OpenCL-CLHPP/releases/tag/v2023.12.14 getInfo<CL_DEVICE_PLATFORM> now returns a different type.

According to the release notes the correct way to do this now is (calling operator() on the returned object):

devices[i]->getInfo<CL_DEVICE_PLATFORM>()();
