CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH -------------------------------------- Controls the default behavior of the following commands for whether or not to search paths provided by standard system environment variables: * :command:`find_program` * :command:`find_library` * :command:`find_file` * :command:`find_path` * :command:`find_package` This is useful in cross-compiling environments. By default this variable is not set, which is equivalent to it having a value of ``TRUE``. Explicit options given to the above commands take precedence over this variable. See also the :variable:`CMAKE_FIND_USE_CMAKE_PATH`, :variable:`CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH`, :variable:`CMAKE_FIND_USE_CMAKE_SYSTEM_PATH`, :variable:`CMAKE_FIND_USE_PACKAGE_REGISTRY`, :variable:`CMAKE_FIND_USE_PACKAGE_ROOT_PATH`, and :variable:`CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY` variables.
