Dev (leetal#103)

* Added a shared build example for macOS as well

* Improve compatibility with more generators (specifically milti-configuration generators like Ninja).

* Refined the caching of variables

* Lots of fixes. Cannot get the mac catalyst builds to work with the xcode generator, but works on all other tested generators.

* Exclude the CMAKE_FIND_ROOT_PATH from macOS builds since it is really only useful when cross-compiling. Also, for other platforms, CMAKE_OSX_SYSROOT_INT is now APPENDED to the CMAKE_FIND_ROOT_PATH to allow users to set own custom paths first for custom find_library behaviours

* Refined some xcode settings as well as fixed a few flaws with the macos builds skipping certain user-defined directories when using any of the find_* commands.

* Fixes for watchos with latest additions

* Added better comment about the symbol visibility

* Exported OSX_ARCHITECTURES as a global property and updated the README to reflect the latest changes.
