Subject: [PATCH] cmake: Remove Auto-Dependency system

While the system helped users get started quickly, it also presented a unique problem by itself. As CMake grew, the code that supported this system became more and more fragile to the point of failing at random, with no indication of why it would fail. Additionally as OBS Studio 28.0 adopted a much nicer system, it is no longer necessary to have this system at all.

As an addition to this change, all systems that could rely on FindModules now do so. This drastically reduces the complexity of the CMake system, while allowing significantly more flexibility with what binaries are really being used. In the best case this should allow a prepared user to build StreamFX by itself within seconds.
