I've build CGAL like explained here.
Everything went well.
But now, I'm using Qt Creator with CGAL.
I've included the libraries in the .pro file :

std::cout << v->point() << std::endl;
}
std::cout << "Hello You" << std::endl;

}
when I compile (with MinGW 4.9.1 32 bit with Qt 5.4.1) I'm having this error :
C:\local\CGAL-4.6\include\CGAL\double.h:191: erreur : '_nextafter' was
not declared in this scope return _nextafter(d1, d2); // works at
least for VC++-7.1
I can't figure out what's wrong...
Can you help me ?
EDIT
It seems that CGAL being compiled with Visual Studio C++ Compiler 10 involves that I have to compile with this compiler and not MinGW.
So I changed compile, I'm now using Microsoft Visual C++ Compiler 10 (amd64) in Qt Creator, but it still don't work. I have an error :
impossible to open 'CGAL-vc100-mt-4.6.lib' file
Here's the complete error (sorry, french version...) :

_nextafter is a Microsoft extension used by CGAL. MinGW doesn't appear to support it.

I use:
Qt 5.15.2 MinGW 32-bit Dynamic for Debug build
Ogre 13.1.1 MinGW Static build
There is a class called ApplicationContextQt that can help to use Qt with Ogre3D but I have errors:
This example is very simple:
main.cpp
#include "Ogre.h"
#include "OgreApplicationContextQt.h"
#include <QGuiApplication>
class MyTestApp : public OgreBites::ApplicationContextQt, public OgreBites::InputListener
{
public:
MyTestApp();
void setup();
bool keyPressed(const OgreBites::KeyboardEvent& evt);
};
MyTestApp::MyTestApp() : OgreBites::ApplicationContextQt("OgreTutorialApp")
{
}
bool MyTestApp::keyPressed(const OgreBites::KeyboardEvent& evt)
{
if (evt.keysym.sym == OgreBites::SDLK_ESCAPE)
{
getRoot()->queueEndRendering();
}
return true;
}
void MyTestApp::setup(void)
{
// do not forget to call the base first
OgreBites::ApplicationContextQt::setup();
}
int main(int argc, char *argv[])
{
QGuiApplication qapp(argc, argv);
MyTestApp app;
app.initApp();
app.getRoot()->startRendering();
app.closeApp();
return qapp.exec();

// It just depends on the actual names of your libraries
// Same for the others unless their file location is decleared under system path.
// If so, you can add that libraries like how you did with opengl
And it is nice to add PRE_TARGETDEPS macros too if you make changes on those libraries so often:
PRE_TARGETDEPS += "E:/ProgramFiles/ogre-13.1.1/lib/OgreBitesQtStatic.a"
You can replace "/"s with "" too.
And the problem with your pro file was: You added library paths as libraries. And then tried to add that libraries from system environment.
I have created Qt class library with Qt VS Tools for visual studio 2019.
I included this library to my Qt project that I too made with Qt VS tools,

In your project file you have set WIN64 but your compiler output states Debug Win32.

I am developping a program with QtCreator in which I use graphviz2.38.
I have done a minimale example to explain. Just consider this small code which transform a dot file in svg file:
#include <QCoreApplication>
#include <graphviz/gvc.h>
#include <graphviz/gvplugin.h>
#include <graphviz/cgraph.h>
#include <graphviz/cdt.h>
#include<iostream>
using namespace std;
void saveImageGV(){
GVC_t *gvc= gvContext();
extern gvplugin_library_t gvplugin_dot_layout_LTX_library;
gvAddLibrary(gvc, &gvplugin_dot_layout_LTX_library);
FILE *fp = fopen(("ancestry.dot"), "r");
Agraph_t *g = agread(fp,0);
gvLayout(gvc, g, "dot");
gvRender(gvc, g, "svg", fopen(("ancestry.svg"), "w"));
gvFreeLayout(gvc, g);
agclose(g);
(gvFreeContext(gvc));
return exit(0);
}
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
saveImageGV();
return a.exec();
}
The compilation options are the following:
QT += core gui

I also provide you an example of graphviz dot code if needed for ancestry.dot:
graph {
a -- b;
b -- c;
a -- c;
d -- c;
e -- c;
e -- a;
}
In my lib folder, I have the following libraries:
ld-linux-x86-64.so.2 libc.so.6 libgvplugin_dot_layout.so.6 libxdot.so.4
libcdt.so.5 libgvc.so.6 libgvplugin_gd.so.6
libcgraph.so.6 libgvplugin_core.so.6 libpathplan.so.4
To load these libraries at execution time, I use the following script:
#!/bin/sh
appname=`basename $0 | sed s,\.sh$,,`
dirname=`pwd`
lib=/lib/
chmod +x $dirname/$appname
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$dirname$lib
echo $LD_LIBRARY_PATH
./$appname "$#"
When I execute my code, I get a segmentation fault ... Any idea of what is happening?

I checked the MyAdde.h and I found this code:
extern LIB_MyAdde_CPP_API void MW_CALL_CONV MyAdde(int nargout, mwArray& c, const mwArray& a, const mwArray& b);
I thinked of that the question is caused by const mwArray& and mwArray const&. I can't understand the reason. I need your help!
It's a linker error , so it has compiled fine but the link failed
It's probably this stuff that is wrong

and these are the build errors:

undefined reference to `Poco::URI::URI(char const*)'
undefined reference to `Poco::URIStreamOpener::defaultOpener()'

undefined reference to `Poco::StreamCopier::copyStream(std::istream&, std::ostream&, unsigned int)'
undefined reference to `Poco::URI::~URI()'
undefined reference to `Poco::URI::~URI()'
The same compiler must be used to compile all three of the below:
Poco library
Qt library
Your application
My hunch is that you use MSVC2012 for #3, you correctly downloaded #2 for MSVC2012, but you did not compile #1 with MSVC2012.
