Thankyou Szilárd,
Headers are available here https://github.com/KhronosGroup/OpenCL-Headers
But I get
CMake Error at cmake/gmxManageOpenCL.cmake:45 (message):
OpenCL is not supported. OpenCL version 1.2 or newer is required.
Call Stack (most recent call first):
CMakeLists.txt:236 (include)
I am setting
OpenCL_include_DIR to C:/Users/Admin/ OpenCL-Headers-master/CL
OpenCL_INCLUDE_DIR OpenCL_Library to C:/Windows/System32/OpenCL.dll
The error file includes

Subject: Re: [gmx-users] Install on Windows 10 with AMD GPU
Dear James,
Unfortunately, we have very little experience with OpenCL on Windows, so I am
afraid I can not advise you on specifics. However, note that the only part of
the former SDK that is needed is the OpenCL headers and loader libraries
(libOpenCL) which is open source software that can be obtained from the
standards body, KHronos. Not sure what the mechanism is for Windows, but for
Linux these components are in packaged in the standard repositories of most
distributions.
However, before going through a large effort of trying to get GROMACS running
on Windows + AMD + OpenCL, you might want to consider evaluating the potential
benefits of the hardware. As these cards are quite dated you might find that
they do not provide enough performance benefit to warrant the effort required
-- especially as, if you have a workstation with significant CPU resources, you
might find that GROMACS runs nearly as fast or faster on the CPU only (that's
because we have very efficient CPU SIMD code for all compute-intensive work).
To do a hopefully easier quick performance evaluation, you could simply boot a
Linux distribution off of an external disk, you can find Linux drivers for them
for Ubuntu 16.04/18.04 at least which you can install and see how well does the
system perform.
I hope that helps!
Cheers,
