Re: [CMake] cmake system library
You could install boost to /usr/local if you're on linux/OSX? That's the standard location for non-system libs, CMake-Modules will look there.

Set BOOST_ROOT to the root of your installing. You need to call this from a clean build directory. Or use the environment variable CMAKE_PREFIX_PATH, which works not only for boost, but all find-modules. To remove a whole set of variable from the cmake cache (to force cmake to search them again), you can do cmake -U *Boost* . in the build dir, this will remove all variables matching *Boost* from the cache.

I think you can set QTDIR in order to give a hint to find_package(Qt[3|4] ...) Set BOOST_ROOT to the root of your installing. You need to call this from a clean build directory. I shall add that you can do that on the command line in order to avoid bury such hint inside your CMakeLists.txt. Note that you can usually find this piece of information in the module documentation (you can get it with cmake --help-module FindBoost ) see: [...] This module reads hints about search locations from variables: BOOST_ROOT - Preferred installation prefix (or BOOSTROOT) BOOST_INCLUDEDIR - Preferred include directory e.g. prefix/include BOOST_LIBRARYDIR - Preferred library directory e.g. prefix/lib Boost_NO_SYSTEM_PATHS - Set to ON to disable searching in locations not specified by these hint variables. Default is OFF. Boost_ADDITIONAL_VERSIONS - List of Boost versions not known to this module (Boost install locations may contain the version) [...] -- Erk Le gouvernement représentatif n'est pas la démocratie -- http://www.le-message.org -- 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://www.cmake.org/mailman/listinfo/cmake

On Saturday 12 January 2013, peterle oberwi wrote: I'm sorry but there is something wrong with my mail prog, please could somebody correct my mistake. Thank you for your answers. But my question is more in general. There defintly some libraries, which don't provide environment variables or other variables for the cmake module. I forgot to mention that I already know the way to set some variables like BOOST_ROOT or whatever, sorry. Also if I install the library to /usr/local the problem is the same. As long as there is a system installed library the command find_package will use this version, as far as I tested it. If there is no way like some special environment varibles or the possibility to force a special version, the system library is used. What I'm looking for is a way like it's done in configure scripts. I can use something like ./configure --use_boost=/home/test/boost_dir. Is there the possiblity to do something like this cmake --use_boost=/home/test/boost_dir. It should be very easy to extend the find_package command. Did you give CMAKE_PREFIX_PATH a try ?
