# CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH

Controls the searching the standard system environment variables by the `find_program()`, `find_library()`, `find_file()`, `find_path()`, and command:find_package commands. 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 `find_program()`, `find_library()`, `find_file()`, and `find_path()` commands take precedence over this variable.

See also the `CMAKE_FIND_USE_CMAKE_PATH`, `CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH`, `CMAKE_FIND_USE_CMAKE_SYSTEM_PATH`, `CMAKE_FIND_USE_PACKAGE_REGISTRY`, and `CMAKE_FIND_USE_PACKAGE_ROOT_PATH` variables.
