The problem has been solved by installing ocl-icd-opencl-dev. I think this package should be mentioned in the installation guide.

Hi,
If you use -DOpenCL_LIBRARY then it has to indicate the location of
libOpenCL.so because you've short-circuited any attempt to find the
library. Check out the advice at
http://manual.gromacs.org/documentation/2019/install-guide/index.html#opencl-gpu-acceleration.
If you've installed system packages for e.lg. amdgpu-pro then you probably
have no need of handling -DOpenCL_*, and particularly not to set them to
values that are in paths that are searched by default. Give an instruction
when you absolutely know what the instruction needs to be, otherwise let
the automation do its job.

Hello!
I can't install Gromacs with OpenCL support. I use Ubuntu 18.04.3 and
Radeon RX550. Commands
cmake .. -DGMX_BUILD_OWN_FFTW=ON -DGMX_GPU=on -DGMX_USE_OPENCL=on
-DOpenCL_LIBRARY=/usr/lib/libOpenCL.so.1.0.0
-DOpenCL_INCLUDE_DIR=/usr/include/CL
make
lead to

What have i tried:
installed opencl-headers and ocl-icd-libopencl1
installed amdgpu-pro (as in manual)
installed fglrx (as in manual)
May there be something else?
