# This is a "subroutine" that can be included to detect the presence of
# pkg-config files in the base system.
#
# The following variables must be defined before including this file:
#
# BUILTIN_FIND_PKGCONFIG_VAR is a list of variables to define. These
# variables take the value of the path to the file that is
# "found".
#
# BUILTIN_FIND_PKGCONFIG.<var> is the list of header files to find, in
# order, on the ${BUILTIN_PKGCONFIG_DIRS}. The variable <var> is set
# to the first path "found" on the filesystem.
#
# After including this file, the following variables are defined:
#
# <var> is the first of the header files listed in
# ${BUILTIN_FIND_PKGCONFIG.<var>} that is "found" in
# ${BUILTIN_PKGCONFIG_DIRS}, or else it is "__nonexistent__".
#
# An example use is:
#
# BUILTIN_FIND_PKGCONFIG_FILES_VAR:= LIB1 LIB2
#
# BUILTIN_FIND_PKGCONFIG_FILES.LIB1= lib1.pc lib-1.0.pc
# BUILTIN_FIND_PKGCONFIG_FILES.LIB2= lib2.pc lib-2.0.pc
# .include "../../mk/buildlink3/find-pkgconfig-files.mk"
