When user defines your 'std' namespace, then Code Completion and Hyperlinks work wrong with standard functions from 'std'.
You can use 'litesql' project or create more simple project.

Steps:
- Create first project with such code:
---------------------------------------------

#include <stdlib.h>
#include <iostream>

namespace std {
    void foo() {
        
    }
}

int main(int argc, char** argv) {
    std::cout << "test\n";
    
    return (EXIT_SUCCESS);
}

---------------------------------------------
- Create second project with such code:
---------------------------------------------

#include <stdlib.h>
#include <iostream>

int main(int argc, char** argv) {
    std::cout << "test\n";
    
    return (EXIT_SUCCESS);
}

---------------------------------------------
- In first and second project type "std::"
==> Code Copletion listbox contain 'foo()' item only
- Hyperlinks on 'cout' doesn't work in both projects.
