Chun-wei Fan 5ffbeeff91 MSVC builds: Improve introspection build process
To avoid confusion, have the NMake Makefiles output the built introspection
files in the same location where the binaries are built for the project
files, according to the Visual Studio version, platform and configuration
where the build is carried out.

Also make generating the introspection NMake snippet portion more robust to
source additions and removals by checking on Makefile changes too.

# 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
