added cmake include for config-generator-based projects

cmake/config_generator_project.cmake

+#
+# cmake include to be used for config generator based projects.
+#
+# Configuration packages for servers can have a very simple CMakeLists.txt like this:

+#   PROJECT(exampleserver-config NONE)
+#   cmake_minimum_required(VERSION 3.5)
+#
+#   set(${PROJECT_NAME}_MAJOR_VERSION 01)
+#   set(${PROJECT_NAME}_MINOR_VERSION 00)
+#   set(${PROJECT_NAME}_PATCH_VERSION 00)
+#   include(cmake/set_version_numbers.cmake)
+#
+#   include(cmake/config_generator_project.cmake)
+#
