# generate_product_version() function
#
# This function uses VersionInfo.in template file and VersionResource.rc file
# to generate WIN32 resource with version information and general resource strings.
#
# Usage:
#   generate_product_version(
#     SomeOutputResourceVariable
#     NAME MyGreatProject
#     ICON ${PATH_TO_APP_ICON}
#     VERSION_MAJOR 2
#     VERSION_MINOR 3
#     VERSION_PATCH ${BUILD_COUNTER}
#     VERSION_REVISION ${BUILD_REVISION}
#   )
# where BUILD_COUNTER and BUILD_REVISION could be values from your CI server.
#
# You can use generated resource for your executable targets:
#   add_executable(target-name ${target-files} ${SomeOutputResourceVariable})
#
# You can specify resource strings in arguments:
#   NAME               - name of executable (no defaults, ex: Microsoft Word)
#   BUNDLE             - bundle (${NAME} is default, ex: Microsoft Office)
#   ICON               - path to application icon (no icon will be included if not provided)
#   VERSION_MAJOR      - 1 is default
#   VERSION_MINOR      - 0 is default
#   VERSION_PATCH      - 0 is default
#   VERSION_REVISION   - 0 is default
#   COMPANY_NAME       - your company name (no defaults)
#   COMPANY_COPYRIGHT  - ${COMPANY_NAME} (C) Copyright ${CURRENT_YEAR} is default
#   COMMENTS           - ${NAME} v${VERSION_MAJOR}.${VERSION_MINOR} is default
#   ORIGINAL_FILENAME  - ${NAME} is default
#   INTERNAL_NAME      - ${NAME} is default
#   FILE_DESCRIPTION   - ${NAME} is default
#   RCFILE_PREFIX      - "Version" is default
