+dnl  Examples:
+dnl     AC_CHECK_SVGC(1.1.0)
+dnl     AC_CHECK_SVGC(1.1.0,,,no,CFLAGS="$CFLAGS -DHAVE_SVGC $SVGC_CFLAGS")
+dnl     AC_CHECK_SVGC(1.1.0,yes,yes,yes,CFLAGS="$CFLAGS -DHAVE_SVGC")

+dnl  If you have to change prefix returned by svgc-config script or change
+dnl  location of svgc-config, you may set environment variable SVGC_CONFIG,
+dnl  for example:
+dnl
+dnl  # export SVGC_CONFIG="svgc-config --prefix=/usr/local"
