As a matter of fact, on Linux distributions that ships CGAL as a regular 
package (Debian, Fedora), that is quite easy.

On Fedora 8, for example, if you want to compile the Triangulation_2 Qt 
demos, 
you need to check first that you have all the needed packages installed:
(after '$' it is the command to type)

$ rpm -q CGAL-devel CGAL-demos-source qt-devel gcc-c++
CGAL-devel-3.3.1-8.fc8
CGAL-demos-source-3.3.1-8.fc8
qt-devel-3.3.8b-2.fc8
gcc-c++-4.1.2-33

If you do not have those package, you need to install them (using 'yum' or 
one 
of it graphical interface).

Then you can, for example, copy the demo/Trianguation_2/ directory to /tmp:

$ cp -a /usr/share/CGAL/demo/Triangulation_2 /tmp

then go into that directory and type 'make', or 'make -j 2' (if you have two 
processors):

$ cd /tmp/Triangulation_2
$ make -j2

That command triggers the compilation. It should run without error, and 
produce the demo executables.

Then run the demos:

$ ./constrained &
$ ./constrained_delaunay_triangulation_2 &
$ ./delaunay_triangulation_2 &
$ ./regular_triangulation_2 &


That's it! :-)
