##section Variables specific to CPack WiX generator
##end
##module
# - CPack WiX generator specific options
#
# 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.
