Shared Vs. Static Libraries

[knight-of-ni]

The cmake build system has been tested successfully from-source on redhat and ubuntu distros.

Today I moved into a (rpm) package building environment and got the unexpected linker error:
../libgen/libgen.so: undefined reference to gConfig'`

This only occurs when attempting to build via the rpmbuild tool.

That is when I remembered the original autotools build system built static, instead of share libraries. Sure enough, changing the cmake files to build Static libraries allowed rpmbuild to successfully a package.

This issue is to remind myself to do two things:

• Learn from @web2wire why we are using static libraries, and whether or not we plan to ever go with shared. I'm sure there is a reason, I'm just looking to understand what it is.
• add the STATIC parameter to each add_library command. I'd like to get initial commit for cmake superbuild #29 merged before I do this to avoid a merge conflict.
