sub20_interface
Tweaked sub20_interface CMake file. Almost perfect, but the libsub.h file must be copied to include/.
More attempts to get catkin compilation. Works for --pkg sub20_interface, but not for plain.
Continued tweaking of CMake configuration.
Finally a working catkin configuration for libsub20.
sub20_interface will now properly download and build libsub20 libraries. However, the libsub20 libraries are not installed, so this will not be distributable. Will need to change libsub20 to REP 0136 type package.
