Title:
  OpenCL disabled on nvidia

Status in darktable package in Ubuntu:
  Confirmed

Bug description:
  OpenCL is not enabled by default.

  Steps to reproduce :
   * install the nvidia driver
   * install darktable
   * run darktable on command line : $darktable -d opencl

  =>
  [opencl_init] could not find opencl runtime library 'libOpenCL'
  0.159268 [opencl_init] could not find opencl runtime library 'libOpenCL.so'
  0.159327 [opencl_init] could not find opencl runtime library 'libOpenCL.so.1'
  0.159333 [opencl_init] no working opencl library found. Continue with opencl disabled
  0.159336 [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.

  Workaround : install package nvidia-opencl-dev

  Should darktable depend on nvidia-opencl-dev ?
