If A and B are in the same source tree under one run of CMake then you 
can use ADD_DEPENDENCIES to make sure A builds before B or vice versa.

If they are in separate source trees with separate runs of CMake then 
this is not supported.  You can try the INCLUDE_EXTERNAL_MSPROJECT 
command, but I don't know if it will do what you want.  You can also add 
a feature request to the bug tracker:
