libGL using memory in console application

I have a KRunner plugin, this of course is gui, and I made a custom profile application to check performance, this is console only, but it's linked with the same options as the gui part.

valgrind --tool=massif on my test application shows memory usage used by libGLcore.so

This is the application I tested with last:

Code:

---

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    a.quit();
}

---

This still shows memory usage by libgl, why?

With all my code there running the test massif says opengl is using 70% of the memory. What is going on?

This is the code, including the CMakeLists.txt file I use to build it:
