# MACOSX_RPATH

Whether this target on OS X or iOS is located at runtime using rpaths.

When this property is set to `TRUE`, the directory portion of the `install_name` field of this shared library will be `@rpath` unless overridden by `INSTALL_NAME_DIR`. This indicates the shared library is to be found at runtime using runtime paths (rpaths).

This property is initialized by the value of the variable `CMAKE_MACOSX_RPATH` if it is set when a target is created.

Runtime paths will also be embedded in binaries using this target and can be controlled by the `INSTALL_RPATH` target property on the target linking to this target.

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