Make SDK consumable by find_package

[skeetsaz]

My CMake skills are not super strong so I forget exactly how this works but I think it needs something like a FindOcvsmdSDK.cmake file so that SDK consumers can use it via find_package. I would expect it to place the SDK headers and library binary somewhere in the build dir and export them as targets for consumption.

I think there is also some bleeding of the dependency headers. If I try to consume Ocvsmd SDK from a separate project then it tries to pull in some libcyphal and spdlog headers as well. Not sure if that is really necessary.

See libhypha (also in the Garage) for an example on how to export header/lib. It doesn't have a bin however
