[Bug 1129409] Re: Nvidia and AMD graphics drivers should indicate whether they provide libcuda.so.1, libOpenCL.so.1, etc.

[Iain Lane]

alternate build-depends don't really work - we always choose the first
one. So I removed your first option & we'll use nvidia-current (please
file another request if this should be changed). I also fixed the PPA
version number. I'll now upload. Thanks!

Bug description:
  The nvidia-cuda-toolkit package needs to depend on a minimum version of the CUDA library included in nvidia-graphics-drivers.
  The current Debian version of nvidia-cuda-toolkit (5.0.35-4) does this on Debian systems by checking the version of libcuda1 and on Ubuntu systems by checking the version of nvidia-current, nvidia-curent-updates, nvidia-experimental-304 or nvidia-experimental-310.

  It would greatly simplify maintenance of packages building against
  libcuda.so.1 and libOpenCL.so.1 if the nvidia-graphics drivers could
  provide virtual packages that reflect the API level, for example,
  libcuda-5.0-1 and libopencl-1.2-1.

  It was decided that the nvidia drivers packages will provide libcuda-5.0-1, libopencl1 and opencl-icd (LP: #763457) virtual packages. Additionally, nvidia-*.shlibs would contain:
  libOpenCL  1 libopencl1
  libcuda    1 libcuda-5.0-1
  libGL 1 libgl1

  Similarly, the amd drivers package will provide libopencl1 and opencl-icd virtual packages, as well as an .shlibs containing:
  libOpenCL  1 libopencl1
  libGL 1 libgl1
