Hi Andrea, thanks for the heads-up. I've encountered a number of problems
getting this project to build and run:

Using Boost 1.52 /CGAL 4.3B1 / QT4 with VS2012 Pro SP1. CGAL installed with
precompiled TAUCS packages.

1. A number of the plug-ins (PCA and jet-fitting for example) refuse to link
with lots of 

liblapack.lib(dgelss.o) : error LNK2026: module unsafe for SAFESEH image.

These can obviously be 'fixed' by setting the linker options to /SAFESEH:No
but it's a pain ....

2. Next issue is that in debug mode these refuse to link with due to
something (not sure which yet) using the release mode MSVCRT libs ...

3. When I run Polyhedron the QT UI comes up but there are a slew of console
errors, examples of which are:

### Loading "nef_io_plugin.dll"...
Error loading "nef_io_plugin.dll": Cannot load library
U:/bin/cgal/demo/polyhedron/Debug/nef_io_plugin.dll: The specified module
could not be found.
### Loading "nef_plugin.dll"...
Error loading "nef_plugin.dll": Cannot load library
U:/bin/cgal/demo/polyhedron/Debug/nef_plugin.dll: The specified module could
not be found.
### Loading "off_plugin.dll"...
Error loading "off_plugin.dll": Cannot load library
U:/bin/cgal/demo/polyhedron/Debug/off_plugin.dll: The specified module could
not be found.

The DLL files *are* in the main solution output folder - so I'm not sure if
this error message is simply misleading and in fact means the DLLs cannot be
loaded because they have some missing dependencies. Having just stepped
through the QT code it is actually hard to tell.

I will investigate this but am asking here just in case this is some weird
but known issue.

Also does anyone have a precompiled version of Polyhedron for Windows which
does load .OFF files? I am indeed especially interested in seeing the
Boolean operations at work.

Thanks.

Jerry.

Note that the Boolean operations are integrated in the Polyhedron demo.
