BUILD_RPATH_USE_ORIGIN
----------------------

Whether to use relative paths for the build ``RPATH``.

This property is initialized by the value of the variable
:variable:`CMAKE_BUILD_RPATH_USE_ORIGIN`.

On platforms that support runtime paths (``RPATH``) with the
``$ORIGIN`` token, setting this property to ``TRUE`` enables relative
paths in the build ``RPATH`` for executables that point to shared
libraries in the same build tree.

Normally the build ``RPATH`` of an executable contains absolute paths
to the directory of shared libraries. Directories contained within the
build tree can be made relative to enable relocatable builds and to
help achieving reproducible builds by omitting the build directory
from the build environment.

This property has no effect on platforms that do not support the
``$ORIGIN`` token in ``RPATH``, or when the :variable:`CMAKE_SKIP_RPATH`
variable is set. The runtime path set through the
:prop_tgt:`BUILD_RPATH` target property is also unaffected by this
property.
