This directory hosts generated GN files for Zircon. These files are created by //build/zircon/create_gn_rules.py and should never be manually edited.
In order to expose a Zircon module to GN, set the MODULE_PACKAGE attribute in its rules.mk build file. The possible values are:
src: the module's sources are published;so: the module is exposed as a precompiled shared library;a: the module is exposed as a precompiled static library; Note that this currently only applies to ulib modules.
