CMakeLists.txt:
###############
set(some_list val1 val2 val3)
add_subdirectory(subdir)
message(STATUS "some_list = ${some_list}")

subdir/CMakeLists.txt:
######################
# append in local scope
list(APPEND some_list val4 val5 val6)
# set in parent scope
set(some_list "${some_list}" PARENT_SCOPE)
