# This is a "subroutine" that can be included to detect whether the
# X11 distribution we are using with pkgsrc has certain X11 components
# built-in to the distribution.
#
# The following variables must be defined before including this file:
#
#    BUILTIN_IMAKE_CHECK is a list of <pkg>:<symbol> pairs, where <pkg>
#	is the package to check for, and <symbol> is the imake symbol
#	to check in the imake config files.
#
# After including this file, the following variables are defined:
#
#    BUILTIN_IMAKE_CHECK.<pkg> is "yes" or "no" depending on whether the
#	specified imake symbol is "true" in the imake config files.
#
# An example use is:
#
# BUILTIN_IMAKE_CHECK:=	Xft2:BuildXftLibrary
# .include "../../mk/buildlink3/imake-check.mk"
#
