SVN commit 589585 by neundorf:
add some special logic so that changing CMAKE_INSTALL_PREFIX still changes all other install locations,
as long as they haven't been set explicitely to some other location, as discussed with Volker Krause

+# this macro implements some very special logic how to deal with the cache
+# by default the various install locations inherit their value from theit "parent" variable
+# so if you set CMAKE_INSTALL_PREFIX, then EXEC_INSTALL_PREFIX, PLUGIN_INSTALL_DIR will
+# calculate their value by appending subdirs to CMAKE_INSTALL_PREFIX
+# this would work completely 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 explicitely to some location, it will always calculate its value from its
+# parents. 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.
