make package_source is broken

[andy5995]

This may be due to changes I've made since ZG was forked; I've never tried it before

To reproduce:

from the ZG source top level directory:

• mkdir build
• cd build
• cmake ..
• make package_source

andy@oceanus:~/src/ZetaGlest/zetaglest-source/build$ make package_source
Run CPack packaging tool for source...
CPack: Create package using TBZ2
CPack: Install projects
CPack: - Install directory: /home/andy/src/ZetaGlest/zetaglest-source
CPack: Create package
CPack: - package: /home/andy/src/ZetaGlest/zetaglest-source/build/zetaglest-0.8.02-Source.tar.bz2 generated.
CPack: Create package using TGZ
CPack: Install projects
CPack: - Install directory: /home/andy/src/ZetaGlest/zetaglest-source
CPack: Create package
^CMakefile:83: recipe for target 'package_source' failed
make: *** [package_source] Interrupt

Seemed to hang. I eventually hit ctrl-c when I saw this:

andy@oceanus:~/src/ZetaGlest/zetaglest-source$ du -sh
18G	.

And now I have a file zetaglest-0.8.02-Source.tar.bz2 that's 1.2GB, which is taking forever to open. Looks like it packed the binaries too.
