Modernize cmake file

- Added JSON_VALIDATOR_SHARED_LIBS to properly handle shared-library
- Bumped minimum cmake to 3.11 to use no-source add_library
- Bumped minimum cmake to 3.14 to properly support FetchContent (FetchContent_MakeAvailable)
- Converted Hunter package manager to FetchContent (It is plenty mature these days)
- Added namespace to exported target
- Made the cmake file compatible with FetchContent
