# MACOSX_RPATH

Whether to use rpaths on Mac OS X.

When this property is set to true, the directory portion of the “install_name” field of shared libraries will be `@rpath` unless overridden by `INSTALL_NAME_DIR`. Runtime paths will also be embedded in binaries using this target and can be controlled by the `INSTALL_RPATH` target property. This property is initialized by the value of the variable `CMAKE_MACOSX_RPATH` if it is set when a target is created.

Policy CMP0042 was introduced to change the default value of MACOSX_RPATH to ON. This is because use of `@rpath` is a more flexible and powerful alternative to `@executable_path` and `@loader_path`.
