Write a script that creates for each of the combinations a separate build tree and then invokes CMake as appropriate. If you want to, you can also use cache-initializer scripts (see the CMake documentation) to set common options in the cache. Since you are building on multiple platforms (presumably not cross-compiling), you'll want to write the script as a CMake script (or Ruby, Python, Lua, whichever suits you best).

I hope this helps, otherwise we'll probably need a bit more information...
