# Author: Fan, Chun-wei
# Common Autotools file used to generate Visual Studio 2008+
# Projects from their templates

# This autotools file, from GLib, can be used in other projects
# that have Visual Studio build support, and is copied into
# $(srcroot)/build/.

# * Input variables:
#
#   MSVCPROJS - List of Projects that should be generated
#
# * Simple tutorial
#
# Add this to Makefile.am where your library/program is built:
#   include $(top_srcdir)/build/Makefile.msvcproj
#   MSVCPROJS = YourProject (can be multiple projects in a single srcdir)
#   YourProject_FILES = $(libyourlib_1_0_SOURCES)
#   YourProject_EXCLUDES = ... # list of sources to exclude, separated by '|', wildcards allowed; use random unsed value if none
#
#   dist-hook: \ # (or add to it if it is already there, note the vs9 items will also call the vs10 items in the process)
#   	$(top_builddir)/win32/vs9/YourProject.vcproj


# Private functions

## Transform the MSVC project filename (no filename extensions) to something which can reference through a variable
## without automake/make complaining, eg Gtk-2.0 -> Gtk_2_0
