Renamed the library to [lib]combine.

With `[lib]Combine`, a CMake file called `[lib]Combine-static-config.cmake` gets generated. Such a CMake file cannot be found on a case-sensitive system (since that kind of filename should be all lower case). Instead, a CMake file called `[lib]combine-static-config.cmake` should be generated.
