DESTDIR
-------
.. include:: ENV_VAR.txt
On UNIX one can use the ``DESTDIR`` mechanism in order to relocate the
whole installation. ``DESTDIR`` means DESTination DIRectory. It is
commonly used by packagers to install software in a staging directory.
For example, running
.. code-block:: shell
make DESTDIR=/package/stage install
will install the software using the installation prefix, e.g. ``/usr/local``,
prepended with the ``DESTDIR`` value which gives ``/package/stage/usr/local``.
The packaging tool may then construct the package from the content of the
``/package/stage`` directory.
See the :variable:`CMAKE_INSTALL_PREFIX` variable to control the
installation prefix when configuring a build tree. Or, when using
the :manual:`cmake(1)` command-line tool's ``--install`` mode,
one may specify a different prefix using the ``--prefix`` option.
.. note::
``DESTDIR`` may not be used on Windows because installation
prefix usually contains a drive letter like in ``C:/Program Files``
which cannot be prepended with some other prefix.
