Use a single name for cmake find_package

@jcar87 adjusted the CMake find_package capabilities, such the config and targets work for the following:

- find_package(sqlite3mc) works
- target_link_libraries(xxx PRIVATE sqlite3mc::sqlite3mc_static)
- OR target_link_libraries(xxx PRIVATE sqlite3mc::sqlite3mc)

This is in line with current CMake convention (one may want to consider having the sqlite3mc::sqlite3mc be an alias for the static recipe if the shared one is not available).
