I was mistaken about the feature existing in CMake 2.6.3.  Bill corrected me
later in the thread.  You will need to use CMake CVS to take advantage of
the ENVIRONMENT test property.  It is quite easy to build CMake CVS, just
like any other CMake project.  I hope it's acceptable for you.  The only
workaround I can think of is to set LD_LIBRARY_PATH manually before your
special test.  If it were called my_special_test you might run the following
commands, for example:

ctest --exclude-regex my_special_test
export LD_LIBRARY_PATH=/my/new/path
ctest --tests-regex my_special_test

Also, I assume you're familiar with how CMake uses RPATH so you don't
usually need to set LD_LIBRARY_PATH in your build tree...?
