dlib::image_load_error: Error, unable to allocate png structure while opening file

[stephanschulz]

I'm on macOS 10.12.6 with Xcode 9.2 and OF 0.10.1 (stable) and the ofxDlib develop branch.

running in to this problem when trying to run face regoncitnion example:

libc++abi.dylib: terminating with uncaught exception of type dlib::image_load_error: Error, unable to allocate png structure while opening file /Applications/of_v0.10.1_osx_release/addons/ofxDlib/example_dlib_dnn_face_recognition/bin/data/bald_guys.png
This is happening because you compiled against one version of libpng, but then linked to another.
Compiled against libpng version: 1.4.12
Linking to this version of libpng: 1.6.16

Move the /Library/Frameworks/Mono.framework folder to a temporary folder
And after I ran the bootstrap.h again.
Now app runs just fine. :)
