Is there a way to an updated variable from parent scope?
For example,
I am in a sub-directory
set(FOO 2 PARENT_SCOPE)
...
<still in sub-directory>
retrieve FOO from PARENT_SCOPE
I know sub-directory would get a copy of FOO, if it existed, when it
was entered.
I played with set/get_property() for this, but which worked ok until I
wanted to store a list
set(FOO a b c PARENT_SCOPE)
set_property(GLOBAL APPEND PROPERTY FOO-LIST FOO)
get_property(my-foo-list GLOBAL PROPERTY FOO-LIST)
foreach (e ${my-foo-list})
message("TEST ${${e}}")
message(TEST2="${e}")
endforeach()
This outputs:
TEST
TEST2="FOO"
Thanks
