+# This macro implements some very special logic how to deal with the cache.
+# By default the various install locations inherit their value from their
+#"parent" variable, so if you set CMAKE_INSTALL_PREFIX, then
+# EXEC_INSTALL_PREFIX, BIN_INSTALL_DIR, LIB_INSTALL_DIR, etc will calculate
+# their value by appending subdirs to CMAKE_INSTALL_PREFIX.
+# This would work just fine without using the cache.
+# But if somebody wants e.g. a different EXEC_INSTALL_PREFIX this value
+# has to go into the cache, otherwise it will be forgotten on the next cmake
+# run. Once a variable is in the cache, it doesn't depend on its "parent"
+# variables anymore and you can only change it by editing it directly.
+# This macro helps in this regard, because as long as you don't set one
+# of the variables explicitly to some location, the value will be computed
+# from parents of the variable in question. So modifying CMAKE_INSTALL_PREFIX
+# later on will have the desired effect.
+# But once you decide to set e.g. EXEC_INSTALL_PREFIX to some special
+# location this will go into the cache and it will no longer depend on
+# CMAKE_INSTALL_PREFIX.
