Will do - I will have to clean up the file a bit though - sundry debug output

It does:
-- wxWidgets_FOUND : TRUE
-- wxWidgets_INCLUDE_DIRS :
D:/wxwidgets/lib/vc120_dll/mswu;D:/wxwidgets/include
-- wxWidgets_LIBRARIES :
debug;D:/wxwidgets/lib/vc120_dll/wxbase30ud.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxbase30u.lib;debug;D:/wxwidgets/lib/vc120_dll/wxmsw30ud_core.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxmsw30u_core.lib;debug;D:/wxwidgets/lib/vc120_dll/wxpngd.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxpng.lib;debug;D:/wxwidgets/lib/vc120_dll/wxtiffd.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxtiff.lib;debug;D:/wxwidgets/lib/vc120_dll/wxjpegd.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxjpeg.lib;debug;D:/wxwidgets/lib/vc120_dll/wxzlibd.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxzlib.lib;debug;D:/wxwidgets/lib/vc120_dll/wxregexud.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxregexu.lib;debug;D:/wxwidgets/lib/vc120_dll/wxexpatd.lib;optimized;D:/wxwidgets/lib/vc120_dll/wxexpat.lib;winmm;comctl32;oleacc;rpcrt4;shlwapi;version;wsock32

An excerpt from the output of CMake, but it is the _only_ file that contains
the wxwidgets_DEFINITIONS macro.

The flag is used, I can see that in the generated files that together comprise
the makefile, but unfortunately the nmake output (even verbose) merely shows
that all manner of flags are incorporated in temporary files.

I cannot be 100% certain, but the flag occurs plainly in the various files, no
extra conditions. So the answer will probably lie in the use of a different
installation.
