Re: lqt: Qt bindings update

["Anders Backman" <andersb@...>]

Ok, great, one step further, at least one left:

Now I added -i  ${BINDING_HEADER}/${BINDING_HEADER} 

Which generates:

#ifndef LQT_HEAD_agxStream_LQT_EndOfArchiveException

#define LQT_HEAD_agxStream_LQT_EndOfArchiveException

#include "lqt_common.hpp"

#include "libname/libname" <<<<

#include "lqt_qt.hpp"

// But then this libname depends on another namespace which is then tried to be included with:

#include <otherlib> 

// which is not correct. Not quite sure where this comes from...

// Either it should not be there at all, or it should be <otherlib/otherlib>

class LQT_EXPORT lqt_shell_otherlib_LQT_EndOfArchiveException : public agxStream::EndOfArchiveException {

the bindings generator (generator.lua) accepts a -i flag, which tells
the headers it must include.
CMakeList.txt is qt specific and uses this flag in the way you
describe. If you bind other libraries you have to supply the correct
include files with the -i option. I have just committed the
possibility of using a header with <...> syntax.
