Organize the code and CMake with subdirectories
- The code is now split into a
common
andbinaries
part, to have code that belongs together in one place. The CMake configuration has been updated accordingly. - Some unneeded "required" components have been removed for Boost and Casacore.
- The
CMake
directory is removed, we now useexternal/aocmmon/CMake
, which provides the same functionality.
