executables, include files and libraries. We use
``GNUInstallDirs.cmake`` which ships with CMake to do the difficult work
of setting a sensible default and setting up CMake cache variables.
These can be overriden when running CMake by setting the
``CMAKE_INSTALL_BINDIR``, ``CMAKE_INSTALL_INCLUDEDIR`` and
``CMAKE_INSTALL_LIBDIR`` cache variables.
The new ``BUILD_PYTHON_BINDINGS`` option (off by default) will enable
building the bindings and the new ``INSTALL_PYTHON_BINDINGS`` option
enables installing them.
