[Gmsh] Compiling in Tetgen

[John Doe]

When I add the files from Tetgen into contrib/Tetgen for the stable
source code tree, the program doesn't build.

make[1]: Leaving directory `/home/foo/gmsh/gmsh-2.2.4/contrib/MathEval'
g++ -g -O2 -o bin/gmsh -Llib -lGmshFltk -lGmshCommon -lGmshGeo
-lGmshMesh -lGmshPost -lGmshPlugin -lGmshCommon -lGmshGraphics

/usr/bin/ld: cannot find -lGmshTetgen
collect2: ld returned 1 exit status
make: *** [link] Error 1
 gmsh-2.2.4>

apparently it is creating a tetgen binary instead of the
libGmshTetgen.a that the linker is looking for.

Thanks,

Juan
