[CMake] How to find wxWidgets with cmake under Windows?

[Werner Smekal]

Hi Bob,

I'm also using wxWidgets 2.8.7 with MinGW/CLI and as Miguel wrote, you  
need to pass some extra parameters so that cmake can find wxWidgets. I  
usually use the zipped wxWidgets package, set the WXWIN environment  
variable, then compile it, and then pass the following to cmake:

cmake -DwxWidgets_LIB_DIR=%WXWIN%\lib\gcc_dll - 
DwxWidgets_CONFIGURATION=msw ../path_to_source

I don't now if you need wxWidgets_CONFIGURATION, but I think you need  
it if you want the debug version (-DwxWidgets_CONFIGURATION=mswd). If  
it still doesn't work, you should enable the debug messages in share/ 
cmake-2.6/Modules/FindwxWidgets.cmake by uncommenting the relevant  
parts between line 119 and 126. This usually gives a lot of  
information and should give you enough hints, where the problem is.

To Miguel,
I use this solution ever since, but as you write this is actually a  
bug/feature, since I think if you don't set the wxWidgets_LIB_DIR  
macro, it assumes vc_dll which is wrong for mingw. So I would be happy  
to do some tests, if this is of any help to you.

Regards,
Werner
