# Sets the variables below and defines no rules, so the consumer keeps their own
# object layout, flag sets and archive step. Name no platform and you get Core
# alone.

# Core compiles against the library's own headers; the platform sources must
# compile with the consumer's flags and config headers (lwipopts.h,
# FreeRTOSConfig.h, mbedtls_config.h, ffconf.h), which is why the two are listed
# separately. Each adapter gates itself on the upstream option it needs, so a
# source the consumer's configuration does not enable compiles to nothing.
