-# libwebp example binaries require dependencies that aren't available for iOS builds.
-# There's also no easy way to invoke the build to *exclude* the example builds.
-# Since we don't need the examples anyway, remove them from the Makefile.
-#
-# As a point of reference, libwebp provides an XCFramework build script that involves
-# 7 separate invocations of make to avoid building the examples. Patching the Makefile
-# to remove the examples is a simpler approach, and one that is more compatible with
-# the existing multibuild infrastructure.
-# 
-# In the next release, it should be possible to pass --disable-libwebpexamples 
-# instead of applying this patch.
