# nuttx_add_dependencies
#
# Description:
#   Wrapper of cmake add_dependencies.
#   At the same time, It also allows adding the header file path
#   exported by the dependent library under NUTTX_APPS_BINDIR/include
#
# Usage:
#   nuttx_add_dependencies( TARGET <string> DEPENDS <list>)
#
# Parameters:
#   TARGET            : target needs to add dependencie
#   DEPENDS           : targets which depends on
# ~~~
