0193   # This macro implements some very special logic how to deal with the cache.
0194   # By default the various install locations inherit their value from their "parent" variable
0195   # so if you set CMAKE_INSTALL_PREFIX, then EXEC_INSTALL_PREFIX, PLUGIN_INSTALL_DIR will
0196   # calculate their value by appending subdirs to CMAKE_INSTALL_PREFIX .
0197   # This would work completely without using the cache.
0198   # But if somebody wants e.g. a different EXEC_INSTALL_PREFIX this value has to go into
0199   # the cache, otherwise it will be forgotten on the next cmake run.
0200   # Once a variable is in the cache, it doesn't depend on its "parent" variables
0201   # anymore and you can only change it by editing it directly.
0202   # this macro helps in this regard, because as long as you don't set one of the
0203   # variables explicitly to some location, it will always calculate its value from its
0204   # parents. So modifying CMAKE_INSTALL_PREFIX later on will have the desired effect.
0205   # But once you decide to set e.g. EXEC_INSTALL_PREFIX to some special location
0206   # this will go into the cache and it will no longer depend on CMAKE_INSTALL_PREFIX.
