Cmake find library issue #49

Open nerdralph opened 6 years ago

nerdralph commented 6 years ago

Cmake doesn't find OpenCL with AMDGPU-pro. As a hack/workaround I added the lib path to the find_library hints: /opt/amdgpu-pro/lib/x86_64-linux-gnu/

I came across lots of bug reports about Cmake multiarch issues, but it's not clear what the "correct" solution is.

Does using the default CMake finder fix things for you. See https://github.com/krrishnarraj/clpeak/pull/45

I tried find_package(OpenCL), but that didn't work. I'm not a cmake fan, so it's still possible it could work with more changes. I'm using cmake 3.5.1 on Ubuntu 16.04.

Yeah. Sorry I haven't used AMDGPU-pro. Seems that path isn't included in the OpenCL module in cmake. https://gitlab.kitware.com/cmake/cmake/blob/master/Modules/FindOpenCL.cmake
