# 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".
