Now all properties related to BUILD_RPATH are linked from the
documentation for BUILD_RPATH.
SKIP_BUILD_RPATH now also refers to BUILD_RPATH.

Projects may set ``BUILD_RPATH`` to specify additional search paths.
The build-tree runtime path will *not* be used for binaries in the
install tree. It will be replaced with the install-tree runtime path
during the installation step. See also the :prop_tgt:`INSTALL_RPATH`
target property.

Other settings that affect the build-tree runtime path include:
* The :prop_tgt:`SKIP_BUILD_RPATH` target property disables setting any
runtime path in the build tree.
* The :prop_tgt:`BUILD_RPATH_USE_ORIGIN` target property causes the
automatically-generated runtime path to use entries relative to ``$ORIGIN``.
* The :prop_tgt:`BUILD_WITH_INSTALL_RPATH` target property causes binaries
in the build tree to be built with the install-tree runtime path.
