Subject: [PATCH] bugfix: macOS did not have IPF support (fixes #1126)

The capsimg.so wasn't copied in the bundle, and even if it was, the path was incorrect under macOS.
This implementation is not necessarily according to macOS "standards", since I've copied capsimg.so in the same location the binary is in, but it does work. :)
