CMP0068

Added in version 3.9.

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:

• BUILD_WITH_INSTALL_RPATH target property

• SKIP_BUILD_RPATH target property

• CMAKE_SKIP_RPATH variable

• CMAKE_SKIP_INSTALL_RPATH variable

Previously, setting BUILD_WITH_INSTALL_RPATH had the effect of setting both the install_name of a target to INSTALL_NAME_DIR and the RPATH to INSTALL_RPATH. In CMake 3.9, it only affects setting of RPATH. However, if one wants INSTALL_NAME_DIR to apply to the target in the build tree, one may set BUILD_WITH_INSTALL_NAME_DIR.

If SKIP_BUILD_RPATH, CMAKE_SKIP_RPATH or 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. It may be set by cmake_policy() or cmake_minimum_required(). If it is not set, CMake warns, and uses OLD behavior.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
