+# This is a very basic file for the new style find_package() search mode,
+# i.e. Config-mode. It is used by KDE4_WRITE_BASIC_CMAKE_VERSION_FILE() from 
+# KDE4Macros.cmake.
+# In this mode find_package() searches for a <package>Config.cmake 
+# file and an associated <package>Version.cmake file, which it loads to check 
+# the version number.
+# This file can be used with configure_file() to generate such a file for a project
+# with very basic logic.
+# It sets PACKAGE_VERSION_EXACT if the current version string and the requested
+# version string are exactly the same and it sets PACKAGE_VERSION_COMPATIBLE
+# if the current version is >= requested version.
+# If this is not good enough for your project, you need to write your own
+# improved <package>Version.cmake file.
+# This file requires the following three variables to be set:
+#   PROJECT_VERSION_MAJOR
+#   PROJECT_VERSION_MINOR
+#   PROJECT_VERSION_PATCH
+
+
+set(PACKAGE_VERSION @PROJECT_VERSION_MAJOR@.@PROJECT_VERSION_MINOR@.@PROJECT_VERSION_PATCH@)
