Does it work if you edit the find_library lines in
cmake/FindVorbis.cmake?
Those are precisely the lines I tried modifying. I tried adding "libogg libogg_static", moving them in front of the original arguments, and even removing the original "ogg ogg_static" arguments. (All three sets of find_library calls, of course)

The DLL names are baked into the import libraries so that's why renaming
didn't work.
Yes, un-renaming the files back to the original names after satisfying CMake was the first work-around I successfully tried , but that is even more counter-intuitive than renaming the files in the first place.

Is this much of a problem?
I actually falsely assumed I was getting video card acceleration because d3d9 was detected even though d3dx9 was not detected (Perhaps I was getting some, but not all possible acceleration?) Ignoring that reason, it's just a nice convenience, especially when you are re-running CMake as often I was. Also, my tweak prefers the latest version of d3d9 instead of the older one that comes by default on Windows 7/Visual Studio 2010. Finally, while debugging the CMakefile.txt I was confused why the d3dx9 library was detected twice, in two different files/variables.
I've been swamped with work, so I haven't been able to confirm on the 5.0 branch. I attached a patch with my changes. It also includes some fixes that allows the skater demo to compile/work on Windows 7 + MSVS 2010. I think some of the CMake if conditions can be collapsed even further, and the vorbis m.lib part has to be made conditional based on MSVC/GCC, but it's a good start.
