# Unfortunately, the order in which CMakeLists.txt code is processed
# matters so we need to be careful about how we order the processing
# of subdirectories. One example is "Compiler flags added late in the
# build are not exported to external build systems #5605"; when we
# integrate with an external build system we read out all compiler
# flags when the external project is created. So an external project
# defined in subsys or ext will not get global flags added by drivers/
# or tests/ as the subdirectories are ordered now.
#
# Another example of when the order matters is the reading and writing
# of global properties such as ZEPHYR_LIBS or
# GENERATED_KERNEL_OBJECT_FILES.

# Arch is placed early because it defines important compiler flags
# that must be exported to external build systems defined in
