CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH

New in version 3.16.

Controls the default behavior of the following commands for whether or not to search paths provided by standard system environment variables:

• find_program()

• find_library()

• find_file()

• find_path()

• 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 CMAKE_FIND_USE_CMAKE_PATH, CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH, CMAKE_FIND_USE_CMAKE_SYSTEM_PATH, CMAKE_FIND_USE_PACKAGE_REGISTRY, CMAKE_FIND_USE_PACKAGE_ROOT_PATH, and CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY variables.
