-We use the CMake program to compile and install the package, and 
-the Stow program to create symlinks to the target directory.
-
-1. Install CMake and Stow
-2. ./config.sh configure

-This will install the tetgen package into the /opt/stow/tetgen directory. 
-Symlinks are created in the /usr/local directory according to the sub-directories 
-of the installed package. Directories of the installation and target directories 
-could be changed by editing the config.sh file.
