Evaluate whether to remove capability to optionally build convenience libraries

[Richard Roberts]

This would simplify the build scripts considerably. Do we benefit by building convenience libraries? If we really want to enforce library dependencies, we could build each subdirectory as a separate shared library (like OpenCV does), e.g. libgtsam_base.so. What do you think, @fdellaert ?

[Frank Dellaert]

We made them for a reason. What was the reason?

[Richard Roberts]

To enforce library dependencies, but I suggested if we want to do that its easier to actually separate the libraries. Convenience libraries are disabled by default FYI because using them doubles the compilation time.

[Frank Dellaert]

In that case I support your cause :-)

[Richard Roberts]

Ok, sounds good, I'll remove it! btw this will prevent linking problems like the one you had the other day with geographiclib .
