create_test_sourcelist
----------------------

Create a test driver and source list for building test programs.

.. code-block:: cmake

  create_test_sourcelist(<sourceListName> <driverName>
                         <tests> ...
                         [EXTRA_INCLUDE <include>]
                         [FUNCTION <function>])

A test driver is a program that links together many small tests into a single
executable.  This is useful when building static executables with large
libraries to shrink the total required size.  The list of source files needed
to build the test driver will be in ``sourceListName``.  ``driverName`` is the
name of the test driver program. The rest of the arguments consist of a list
of test source files and can be semicolon separated.  Each test source file
should have a function in it that is the same name as the file with no
extension (``foo.cxx`` should have ``int foo(int, char*[]);``). ``driverName``
will be able to call each of the tests by name on the command line.  If
``EXTRA_INCLUDE`` is specified, then the next argument is included into the
generated file. If ``FUNCTION`` is specified, then the next argument is taken
as a function name that is passed pointers to ``argc`` and ``argv``.  This can
be used to add extra command line processing to each test.  The
``CMAKE_TESTDRIVER_BEFORE_TESTMAIN`` cmake variable can be set to have code
that will be placed directly before calling the test ``main`` function.
``CMAKE_TESTDRIVER_AFTER_TESTMAIN`` can be set to have code that will be
placed directly after the call to the test ``main`` function.
