Ok, heres an example with only the relevant stuff:

main.aap
--------------
:child foo1.aap
:child foo2.aap


foo1.aap
--------------
gtkdir {virtual} :
     GTK_BIN = "dir coming from file_path()"

gtklib : gtkdir
     _top.GTK_LIBS = GTK_BIN

all : gtklib


foo2.aap
---------------
LIBS = $_top.GTK_LIBS


Now execute the main recipe to get an error from foo2
