FetchContent downloads type_safe on every CMake generation

Apparently it fails to find the type_safe package every time and thus redownloads it. I suggest you just reintroduce type_safe as a Git submodule, remove find_package and include type_safe in your CMakeLists.txt as a subdirectory: there really isn't a need for FetchContent in this case. (Correct me if I'm wrong)
By the way, this library is extremely useful. Thanks for creating it!
It prints Fetching type_safe every time, but doesn't actually re-download it again unless you delete it from the build folder.

Are you sure? I'm not that familiar with CMake but there is indeed a noticeable delay in the generation once the Fetching type_safe message shows up. Plus, it seems that it's not displayed every time; rather, it's only shown if the package is missing.
The documentation says so: https://cmake.org/cmake/help/latest/module/FetchContent.html
Got it, thanks.
