Try the latest FindwxWidgets.cmake. You can just replace this file in
your installation (make a backup of the current one, of course) or put
it in a local modules dir. It can be found at:

http://public.kitware.com/cgi-bin/viewcvs.cgi/Modules/FindwxWidgets.cmake?root=CMake&view=markup

Also, if wxWidgets_LIB_DIR is not found, you can set it manually or in
the CMakeLists.txt. Although, I recognize it would be better for the
module to find it, which it should do.

You can use the following, although this is unrelated to the above problem:

------
# no need for the if structure if using REQUIRED
FIND_PACKAGE(wxWidgets REQUIRED <libs needed>)
INCLUDE(${wxWidgets_USE_FILE})
...
TARGET_LINK_LIBRARIES(acrls ITKCommon ITKIO ${wxWidgets_LIBRARIES})
------

Hope this helps.
