Subject: [PATCH] Fixed Apple framework object dependencies

Updated target object dependencies for Apple static and dynamic frameworks
to use TARGET_EXISTS for osd_gpu_obj to allow correct linking when no
OSD_GPU targets are enabled. We'll likely revisit these targets further
for future releases of OpenSubdiv.

Fixes #1224
Fixes #1236
