I’ve been trying to learn C++ and I started to learn about GUIs, but I’ve encountered some problems.
I am using wxWidgets 3.2.5, downloaded it by source on the official website but I can’t get It to work – whenever I try to run the example you can download on GitHub (https://github.com/lszl84/wx_cmake_template/tree/master) It says 'wx/wxprec.h' file not found.

You can correct the error by including the complete path to the #include, but the nested #include in the .h files will now give you file not found (ex. I corrected 'wx/wx.h' to /Users/alessandrodoro/wx_cmake_template/wxWidgets-3.2.5/include/wx/wx.h" , but inside wx.h there are ~81 #include 'wx/...' and every single one of them gives me error).

I tried including the workspace to path in C/C++ configurations as ${workspaceFolder}/src/**

/Users/alessandrodoro/wx_cmake_template/wxWidgets-3.2.5/include/wx/**

But it does not seem to change anything.

I’m using Mac Ventura 13.4.1 (M1) with VSCode

My main.cpp file is:

// wxWidgets "Hello world" Program
// For compilers that support precompilation, includes "wx/wx.h".
//#include <wx/wxprec.h>
#include "/Users/alessandrodoro/wx_cmake_template/wxWidgets-3.2.5/include/wx/wxprec.h"
#ifndef WX_PRECOMP
//#include <wx/wx.h>
#include "/Users/alessandrodoro/wx_cmake_template/wxWidgets-3.2.5/include/wx/wx.h"
#endif
class MyApp : public wxApp
{
public:
    virtual bool OnInit();
};
class MyFrame : public wxFrame
{
public:
    MyFrame(const wxString &title, const wxPoint &pos, const wxSize &size);

private:
    void OnHello(wxCommandEvent &event);
    void OnExit(wxCommandEvent &event);
    void OnAbout(wxCommandEvent &event);
    wxDECLARE_EVENT_TABLE();
};
enum
{
    ID_Hello = 1
};
wxBEGIN_EVENT_TABLE(MyFrame, wxFrame)
    EVT_MENU(ID_Hello, MyFrame::OnHello)
        EVT_MENU(wxID_EXIT, MyFrame::OnExit)
            EVT_MENU(wxID_ABOUT, MyFrame::OnAbout)
                wxEND_EVENT_TABLE()
                    wxIMPLEMENT_APP(MyApp);
bool MyApp::OnInit()
{
    MyFrame *frame = new MyFrame("Hello World", wxPoint(50, 50), wxSize(450, 340));
    frame->Show(true);
    return true;
}
MyFrame::MyFrame(const wxString &title, const wxPoint &pos, const wxSize &size)
    : wxFrame(NULL, wxID_ANY, title, pos, size)
{
    wxMenu *menuFile = new wxMenu;
    menuFile->Append(ID_Hello, "&Hello...tCtrl-H",
                     "Help string shown in status bar for this menu item");
    menuFile->AppendSeparator();
    menuFile->Append(wxID_EXIT);
    wxMenu *menuHelp = new wxMenu;
    menuHelp->Append(wxID_ABOUT);
    wxMenuBar *menuBar = new wxMenuBar;
    menuBar->Append(menuFile, "&File");
    menuBar->Append(menuHelp, "&Help");
    SetMenuBar(menuBar);
    CreateStatusBar();
    SetStatusText("Welcome to wxWidgets!");
}
void MyFrame::OnExit(wxCommandEvent &event)
{
    Close(true);
}
void MyFrame::OnAbout(wxCommandEvent &event)
{
    wxMessageBox("This is a wxWidgets' Hello world sample",
                 "About Hello World", wxOK | wxICON_INFORMATION);
}
void MyFrame::OnHello(wxCommandEvent &event)
{
    wxLogMessage("Hello world from wxWidgets, ginger!");
}

My c_cpp_properties.json reads:

I saw an answer that said to try g++ `wx-config --cxxflags` -o out *.cpp `wx-config --libs` but it generates this error:

tempCodeRunnerFile.cpp:2:2: error: unterminated conditional directive

#ifndef WX_PRECOMP

I am new to C++ and have little to no idea of what I’m doing – I tried following all the tutorials available to my situation but with no success.
All the help is appreciated.
