------------------------------+--------------------------------
 After the fix for ticket #41358, libQGLViewer.dylib builds successfully
 for x86_64, but the link of the example program called animation fails.
 libQGLViewer.dylib is built for x86_64 only and the example program is
 trying to link i386.
