# Author: Fan, Chun-wei
# Common autotools file for constructing the g-ir-scanner and
# g-ir-compiler command lines for Visual Studio builds.
# This is copied from $(srcroot)/build from the gobject-introspection
# project, which may be included in projects that support both
# Visual Studio builds and introspection.
# * Input variables:
#
# MSVC_INTROSPECT_GIRS - List of .gir's that should be built
# in the NMake Makefiles
#
# * Simple tutorial
#
# Add this to Makefile.am where your library/program is built:
# (Either YourLib_1_0_gir_MSVC_LIBS or YourLib_1_0_gir_MSVC_PROGRAM
# is required unless --headers-only is specified in
# YourLib_1_0_gir__MSVC_SCANNERFLAGS)
#
# include $(top_srcdir)/build/Makefile.msvc-introspection
# MSVC_INTROSPECT_GIRS = YourLib-1.0.gir
