Honor OPTIONAL_COMPONENTS when finding SFML

Browse Source 
The "main" component is not available everywhere, but passing it to the
find_package(SFML) call via the OPTIONAL_COMPONENTS still fails the call
on platforms like Linux.

This commit enables SFML to be used the same in a cross-platform fashion
without forcing consumers to put custom logic around importing SFML.
Example that works with this commit, but break before:

    find_package(SFML REQUIRED graphics OPTIONAL_COMPONENTS main)
    target_link_libraries(dummy PRIVATE SFML::graphics)
    if(SFML_MAIN_FOUND)
      target_link_libraries(dummy PRIVATE SFML::main)
    endif()
