Oops, typo in there. nvdia should be nvidia.

Orion, thanks for your interest.

As far as I can tell this is a non-standard installation of the driver. NVIDIA nor the distro maintainers (RedHat and Fedora) support RPMFusion. I don't feel it's a maintainable practice to add paths for every possible location someone may decided to put the driver. I'm surprised they can put it in a different location and have applications that depend on it link properly at run-time.

Please look at the documentation for CMake's find_library() for ways of adding additional system paths for CMake to search in. find_library_local_first() will call find_library() allowing CMake to look in all of the locations it knows about (see the docs again to see where find_library looks).

Well, as far as I know, rpmfusion is *the* recommended way to install the nvidia binary drivers on Fedora, so it is not at all uncommon. Run time is handled via /etc/ld.so.conf.d/. Anyway, it is your call. -DCMAKE_LIBRARY_PATH=/usr/lib/nvidia certainly works as well.

I'm curios what the contents of /etc/ld.so.conf.d are. Could you paste it in or attach it if it's really large?

I'm trying to decide if I should bring up CMake using this information somehow to help locate libraries on the system, since distributions can put things in non-standard locations and this seems like a candidate for a list of these locations.

Hard to say it that is a good idea or not. As runtime does not always equal what you want at build time. Anyway, I've attached the contents of mine. Obviously this could be very different depending on what packages are installed.

Could you attach the list of files that are installed by the nvidia driver RPM? I'm trying to determine where the 32 and 64 bit cuda libraries are.

I can add that the same issue is present on Ubuntu (11.10 in my case), but here the location is /usr/lib/nvidia-current.

/etc/ld.so.conf:
  include /etc/ld.so.conf.d/*.conf

/etc/ld.so.conf.d//x86_64-linux-gnu_GL.conf:
  /usr/lib/nvidia-current
  /usr/lib32/nvidia-current

I think it would be a good idea to have CMake parse the ld.so.conf, at least for the cuda driver lib.
