FYI fixed NETGEN plugin configuration problem

Hi

I compiled netgen for Salome with the necessary patches. Then I tried to build the NETGEN plugin.

It seems the configuration script creates a temporary libNETGEN.so library in order to test the correct installation of the netgen object files. But the configuration failed due to some undefined references. (See the config.log file below).

I fixed this problem by adding "csgparser.o" & "extrusion.o" to the $CXX flag in the configuration file.

Presumably my version of netgen has moved some of the code into different units.
