# Lists of build directories.
#
# CONTEXTDIRS include directories that have special, one-time pre-build
#   requirements.  Normally this includes things like auto-generation of
#   configuration specific files or creation of configurable symbolic links
# CLEANDIRS are the directories that will clean in.  These are
#   all directories that we know about.
# KERNDEPDIRS are the directories in which we will build target dependencies.
#   If NuttX and applications are built separately (CONFIG_BUILD_PROTECTED or
#   CONFIG_BUILD_KERNEL), then this holds only the directories containing
#   kernel files.
# USERDEPDIRS. If NuttX and applications are built separately (CONFIG_BUILD_PROTECTED),
#   then this holds only the directories containing user files. If
#   CONFIG_BUILD_KERNEL is selected, then applications are not build at all.
