Re: trouble installing CGAL ipelets

In Ipe 7.1.7, the file extension for dynamic library has changed from
.so to .dylib on Mac OS X, to satisfy Apple's desire to be different.

The instructions https://3d.bk.tudelft.nl/hledoux/blog/ipe-cgal-ipelets/
seem to be for Ipe 7.1.6 or earlier, as they copy *.so files.

So probably all you need to do is to rename the .so files in
/Users/lenka/.ipe/ipelets to .dylib.

(And CGAL should update their build script.)

Cheers,
 Otfried
