# CPack WiX generator specific options
#
# #section Variables specific to CPack WiX generator #end #module
#
# The following variables are specific to the installers built on
# Windows using WiX.  #end #variable
#
# ::
#
#   CPACK_WIX_UPGRADE_GUID - Upgrade GUID (Product/@UpgradeCode)
#
#
#
# Will be automatically generated unless explicitly provided.
#
# It should be explicitly set to a constant generated gloabally unique
# identifier (GUID) to allow your installers to replace existing
# installations that use the same GUID.
#
# You may for example explicitly set this variable in your
# CMakeLists.txt to the value that has been generated per default.  You
# should not use GUIDs that you did not generate yourself or which may
# belong to other projects.
#
# A GUID shall have the following fixed length syntax:
# XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
#
# ::
#
#   (each X represents an uppercase hexadecimal digit)
#
# #end #variable
#
# ::
#
#   CPACK_WIX_PRODUCT_GUID - Product GUID (Product/@Id)
#
#
#
# Will be automatically generated unless explicitly provided.
#
# If explicitly provided this will set the Product Id of your installer.
#
# The installer will abort if it detects a pre-existing installation
# that uses the same GUID.
#
# The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.
# #end #variable
#
# ::
#
#   CPACK_WIX_LICENSE_RTF - RTF License File
#
#
#
# If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.
#
# If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly
# converted to RTF by the WiX Generator.
#
# With CPACK_WIX_LICENSE_RTF you can override the license file used by
# the WiX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an
# unsupported format or the .txt -> .rtf conversion does not work as
# expected.
#
# #end
#
# #variable CPACK_WIX_PRODUCT_ICON - The Icon shown next to the program
# name in Add/Remove programs.
#
# If set, this icon is used in place of the default icon.
#
# #end
#
# #variable CPACK_WIX_UI_BANNER - The bitmap will appear at the top of
# all installer pages other than the welcome and completion dialogs.
#
# If set, this image will replace the default banner image.
#
# This image must be 493 by 58 pixels.
#
# #end
#
# #variable CPACK_WIX_UI_DIALOG - Background bitmap used on the welcome
# and completion dialogs.
#
# If this variable is set, the installer will replace the default dialog
# image.
#
# This image must be 493 by 312 pixels.
#
# #end
#
# #variable CPACK_WIX_PROGRAM_MENU_FOLDER - Start menu folder name for
# launcher.
#
# If this variable is not set, it will be initialized with
# CPACK_PACKAGE_NAME
#
# #end #variable CPACK_WIX_CULTURES - Language(s) of the installer
#
# Languages are compiled into the WixUI extension library.  To use them,
# simply provide the name of the culture.  If you specify more than one
# culture identifier in a comma or semicolon delimited list, the first
# one that is found will be used.  You can find a list of supported
# languages at:
# http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm
#
# #end #variable CPACK_WIX_TEMPLATE - Template file for WiX generation
#
# If this variable is set, the specified template will be used to
# generate the WiX wxs file.  This should be used if further
# customization of the output is required.
#
# If this variable is not set, the default MSI template included with
# CMake will be used.
#
# #end #variable CPACK_WIX_EXTRA_SOURCES - Extra WiX source files
#
# This variable provides an optional list of extra WiX source files
# (.wxs) that should be compiled and linked.  The full path to source
# files is required.
#
# #end #variable CPACK_WIX_EXTRA_OBJECTS - Extra WiX object files or
# libraries
#
# This variable provides an optional list of extra WiX object (.wixobj)
# and/or WiX library (.wixlib) files.  The full path to objects and
# libraries is required.
