No, I never tried that, I need the dll for my program.

I tested it, and it doesn't work, although wxWidgets_LIB_DIR is set  
correctly for MinGW. But the problem is, that the module looks for the  
wrong libraries:

FIND_PATH(wxWidgets_LIB_DIR
         NAMES wxpng.lib wxpngd.lib
         PATHS
         ${WX_ROOT_DIR}/lib/${WX_LIB_DIR_PREFIX}_dll   # prefer shared
         ${WX_ROOT_DIR}/lib/${WX_LIB_DIR_PREFIX}_lib
         DOC "Path to wxWidgets libraries?"
         NO_DEFAULT_PATH
         )

The MinGW compiler toolset adheres to the library naming convention  
for Linux and therefore the corresponding libraries are called

libwxpng.a and libwxpngd.a

So either add these names to NAME, or use another variable? I think  
any other windows compiler would name the library wxpng.lib.

HTH,
Werner
