yes; if you go in wxLua/modules/wxbind/build and type

   nmake -fmakefile.vc WXLUASETUP_DIR=c:\mydir WXLUABINDLIB_DIR=c:\

then a wxbind library with your custom wxluasetup.h (which must be in 
c:\mydir) is created and put in c:\

it's in wxbind/ and not directly in modules/ because it regards wxbind 
module only.
And it's not in wxbind/include/ because that dir _must_ always be 
included. the official wxluasetup.h must be something which we can 
decide to include or to exclude at will (e.g. when building user's 
custom wxbind we still need to include wxbind/include folder but we do 
not include the wxbind/setup one; rather than we include the folder 
specified by WXLUASETUP_DIR).

If we keep wxluasetup.h in the wxbind/include then even if we add to 
include search paths WXLUASETUP_DIR we cannot be 100% sure that compiler 
will choose the wxluasetup.h found in WXLUASETUP_DIR rather than the one 
in wxbind/include...

using this form we force the user to keep his custom wxluasetup.h in a 
setup/ subfolder...

well, wxlua & wxluaedit applications do not include wxluasetup.h; only 
wxLua modules (and wxLuaCan) do.

I thought it was possible to build wxLua applications (in C++) which do 
not include wxluasetup.h... is it right ?
