Behavior is as documented so it is at most a missing feature. Why do you need NO_DEFAULT_PATH when looking for GL libraries? You're looking for a system-provided library so why tell CMake not to search the system paths it knows? >> The paths you added are ignored if I set >> NO_DEFAULT_PATH.

That is also the behavior of CMAKE_SYSROOT and if >> CMAKE_OSX_SYSROOT is to be merged/made obsolete by CMAKE_SYSROOT, then the We still don't understand the right way to combine them. In fact this might be a distinguishing case between them. Using CMAKE_SYSROOT is an explicit choice to use in typical cross-compiling cases. Using CMAKE_OSX_SYSROOT is common in host-only builds. I see no reason that CMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY should cause library searches to be restricted to CMAKE_OSX_SYSROOT when no CMAKE_FIND_ROOT_PATH or CMAKE_SYSROOT is set. CMAKE_OSX_SYSROOT is about where the system provided SDKs are found, not an isolated cross-compiling development tool prefix. >> behavior should be the same in CMake 2.8.12.1. We will not be changing non-regressed behavior in a tweak release. > I pushed the osx-sysroot-no-system topic to illustrate what I mean by this. > I haven't tested it, because I'm not familiar enough with mac, so I haven't > merged it to next yet. Don't mess with the "CMAKE_*_IMPLICIT_*" variables. Those are for link line computation, not "find_*" commands. -Brad -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
