I got bitten by this bug today in 2.8.4 so I am glad Allen found it
earlier, and it will be fixed in 2.8.5.

My own use case is I don't particularly care about the order of the tests except that one
of them is dependent on most of the rest as I discovered when the
tests were run in an unusual order with CMake-2.8.4.  Running the set_tests_properties
command according to
http://cmake.org/cmake/help/cmake-2-8-docs.html#prop_test:DEPENDS
works around the issue and is probably a good idea in general when one
test depends on others.

Note, however, that although most PLplot users are presumably using
cmake-2.8.x, PLplot users are still allowed to use cmake-2.6.4 (and
that will continue a bit longer). Thus, I had to surround the
set_tests_properties command with this CMake version check;

if(CMAKE_MAJOR_VERSION EQUAL 2 AND NOT CMAKE_MINOR_VERSION LESS 8)

because DEPENDS does not exist in cmake-2.6.x as a test property
according to the cmake-2.6.x documentation.
