Comment (by kenneth.f.cunningham@…):

 I was curious whether libSDL2 linked to or depended in any way on the
 10.7SDK once built, but it doesn't appear to -- I have to read more about
 how this works. I guess it just uses the headers and other information in
 the 10.7SDK to run the build correctly...I wonder if this approach might
 work for any other software on 10.6 too (like qt5, for example...).
