To elaborate, I'm specifically getting this error message:

CMake Error at vfx/CMakeLists.txt:74 (install):
  install TARGETS given target "messenger" which does not exist in this
  directory.

And this is what my INSTALL() command looks like:

install( TARGETS messenger ARCHIVE DESTINATION "${target_bin_dir}" )


I have no idea what the error message above means. At first I thought it was
due to the ordering in which I defined my projects, but I'm not sure that's
true. The 'messenger' project is defined in another sibling directory,
perhaps that is the issue?
