CMake adds these project-destination +prefixes to :variable:`CMAKE_SYSTEM_PREFIX_PATH` by default in order to +support building a series of dependent packages and installing them into +a common prefix. Set ``CMAKE_FIND_NO_INSTALL_PREFIX`` to ``TRUE`` +to suppress this behavior. + +The :variable:`CMAKE_SYSTEM_PREFIX_PATH` is initialized on the first call to a +:command:`project` or :command:`enable_language` command. Therefore one must +set ``CMAKE_FIND_NO_INSTALL_PREFIX`` before this in order to take effect. A +user may set the variable as a cache entry on the command line to achieve this. + +Note that the prefix(es) may still be searched for other reasons, such as being +the same prefix as the CMake installation, or for being a built-in system +prefix. |
