Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
This adds a CMake installer to conserve targets and properties on install, so CMake users do not need to write `FindBlosc2.cmake` files anymore. This also helps to preserve transitive dependencies on CMake targets, especially useful for fully static builds, e.g., for Python wheels.
