Only if CppUnit is only meant to work only with the GCC compiler or you will
only ever use the GCC compiler.  If there is a chance you'll want to compile
your code with MSVC or some other compiler or you wish to contribute your
find modules back to CMake you should consider using the find_library() and
find_path() commands to locate the cppunit header files and library.

This is usually fairly simple to do and most people encapsulate this
activity in a Find* macro.  Looks like someone has already done some work to
make a FindCppUnit macro but it never got cleaned up and checked into CMake.

Just set your CMAKE_MODULE_PATH and call FIND_PACKAGE(CppUnit) and then
react accordingly based on the cache variables it provides.  You should
probably also take advantage of CPPUNIT_FOUND in determining if it's
appropriate to build and link the test code.

Depending on how many test executables you have, you may want to make a
small macro wrapper that calls ADD_EXECUTABLE() then ADD_TEST() that way you
can keep your CMake code to a minimum.
