# 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
#   YourLib_1_0_gir_NAMESPACE = YourLib # This is optional
#   YourLib_1_0_gir_VERSION = 1.0 # This is optional
#   YourLib_1_0_gir_MSVC_LIBS = yourlib-1.0
#   YourLib_1_0_gir_MSVC_FILES = $(libyourlib_1_0_SOURCES)
