Sorry about this problem which by coincidence also came up today for libLASi (which has a similar install location system). I have just made a change for both projects so this bad human-engineering issue should be eliminated. The short story is if you start with a clean source tree and initially empty (separate) build tree (so no stale files from previous builds are hanging around) then cmake or ccmake with the command-line option -DCMAKE_INSTALL_PREFIX=whatever always works fine. However, inconsistencies in install locations can occur, if you have a stale cache hanging around or if you do not specify the -DCMAKE_INSTALL_PREFIX option when invoking ccmake, and you attempt to change CMAKE_INSTALL_PREFIX from the ccmake GUI instead. What happens internally is that the value of CMAKE_INSTALL_PREFIX is cached and its also taken as the _default_ value of the install prefix for every other install location variable before they are cached as well. Once they are cached, then ccmake gives you the opportunity to change them to something else, but if you don't specify the -DCMAKE_INSTALL_PREFIX option for the ccmake command, then the cached values will all refer to /usr/local, and will _all_ have to be changed consistently by the user. Now we get to the bad human engineering part. Before I used MARK_AS_ADVANCED for all those generated install locations. Thus, they were by default (unless they hit the t option) hidden from ccmake users so they could not see when they were inconsistent with what they wanted. So that was a nasty trap inadvertently set for the user. With MARK_AS_ADVANCED removed, they are now diplayed in all circumstances, and the users therefore have a chance to specify the desired install locations. And, of course, if they ever get tired of doing that, they can also avoid the problem altogether by specifying the -DCMAKE_INSTALL_PREFIX option for the ccmake command. Sorry, Jerry, you were caught by this (inadvertent) trap, but I hope it is all straightened out for you now. Alan __________________________ Alan W.
