Subject: [PATCH] Fix CMake Install: Find*.cmake Modules

Install the CMake modules in `cmake/` into our install
prefix. If we build with external dependencies for LZ4 and ZLIB_NG,
will need those Modules to populate our CMake import targets in
`Blosc2Config.cmake` during the `find_dependency` calls (which
are just wrappers for `find_package`).
