-------------------------------------------
It's often necessary or useful when debugging driver issues or testing new
branches to run against a local build of Mesa without doing a system-wide
install. To do this, choose a temporary location for the install. A directory
called ``installdir`` inside your mesa tree is as good as anything. All of the

.. code-block:: console
meson devenv -C builddir glxinfo
This will run the given command against the build in ``builddir``. Note that meson
will ``chdir`` into the directory first, so any relative paths in the command line
will be relative to ``builddir`` which may not be what you expect.
