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.
