I don't know if it's best, but the way I handle this is by defining
${ext1_includes} and ${ext1_definitions} in a common place accessible to
both subA1 and subA2. I use a separate CMakeVars.txt for each project
that defines variables which a dependent might need to communicate with
that project. You could also use [set|get]_target_property.
Then subA1 and subA2 simply have ${ext1_includes} in their
include_directories() invocation.
