CMakes piles up various generations of idioms so there are multiple ways of doing it, but personally I’ve learned to steer away from find_package() and other magical functions. Get all your dependencies as subdirectories (whichever way you prefer) and use add_subdirectory(). Use find_package() only in so-called "config" mode where you explicitly instruct cmake where to find the config for large precompiled dependencies only |

Yes, config packages are better. But I think doing find_package everywhere is better. Assuming you install an SDK for others to use your project. If you're a "product", vendor away. The issue comes when you want to vendor X and Y and both vendor Z independently. Then you're stuck de-vendoring at least one and figuring out how to provide it yourself internally. IMO, better to just let Z make its own install tree and find it as a package from there.
One can write good Find modules, but there is some "taste" involved. I wish we had more good examples to use as templates.
