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