# This is a "subroutine" that can be included to detect the presence of
# libraries in the base system.
#
# The input variable is BUILDLINK_FIND_LIBS, which is a list of library
# names, e.g. ncurses, iconv, etc., that will be sought in the base
# system. BUILTIN_LIB_FOUND.<lib> is set to "yes" or "no" depending
# on the result of the search.
#
# An example use is:
#
# BUILDLINK_FIND_LIBS:= intl iconv
# .include "../../mk/buildlink3/find-libs.mk"
# # ${BUILTIN_LIB_FOUND.intl} and ${BUILTIN_LIB_FOUND.iconv} are now
# # either "yes" or "no".
