``RPATH`` settings on macOS do not affect ``install_name``.
|
|
|
|
|
|
|
|
|
|
CMake 3.9 and newer remove any effect the following settings may have on the
|
|
|
|
|
``install_name`` of a target on macOS:
|
|
|
|
|
|
|
|
|
|
* :prop_tgt:`BUILD_WITH_INSTALL_RPATH` target property
|
|
|
|
|
* :prop_tgt:`SKIP_BUILD_RPATH` target property
|
|
|
|
|
* :variable:`CMAKE_SKIP_RPATH` variable
|
|
|
|
|
* :variable:`CMAKE_SKIP_INSTALL_RPATH` variable
|
|
|
|
|
|
|
|
|
|
Previously, setting :prop_tgt:`BUILD_WITH_INSTALL_RPATH` had the effect of
|
|
|
|
|
setting both the ``install_name`` of a target to :prop_tgt:`INSTALL_NAME_DIR`
|
|
|
|
|
and the ``RPATH`` to :prop_tgt:`INSTALL_RPATH`. In CMake 3.9, it only affects
|
|
|
|
|
setting of ``RPATH``. However, if one wants :prop_tgt:`INSTALL_NAME_DIR` to
|
|
|
|
|
apply to the target in the build tree, one may set
|
|
|
|
|
:prop_tgt:`BUILD_WITH_INSTALL_NAME_DIR`.
|
|
|
|
|
|
|
|
|
|
If :prop_tgt:`SKIP_BUILD_RPATH`, :variable:`CMAKE_SKIP_RPATH` or
|
|
|
|
|
:variable:`CMAKE_SKIP_INSTALL_RPATH` were used to strip the directory portion
|
|
|
|
|
of the ``install_name`` of a target, one may set ``INSTALL_NAME_DIR=""``
|
|
|
|
|
instead.
|
|
|
|
|
|
|
|
|
|
The ``OLD`` behavior of this policy is to use the ``RPATH`` settings for
|
|
|
|
|
``install_name`` on macOS. The ``NEW`` behavior of this policy is to ignore
|
|
|
|
|
the ``RPATH`` settings for ``install_name`` on macOS.
|
|
|
|
|
|
|
|
|
|
This policy was introduced in CMake version 3.9. CMake version
|
|
|
|
|
|release| warns when the policy is not set and uses ``OLD`` behavior.
|
|
|
|
|
Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW``
|
|
|
|
|
explicitly.
