I solved my problem with :

// Absolute / relative modes
if (getTrackerPressed(g_ActionButtons[LOCK_VIEW])) {
    g_mouse_state.x = 0;
    g_mouse_state.y = 0;
    POINT p;
    if (GetCursorPos(&p)) {
        g_mouse_abs_x = p.x;
        g_mouse_abs_y = p.y;
    }
    g_mouse->SetMode(Mouse::MODE_RELATIVE);
}
else if (getTrackerReleased(g_ActionButtons[LOCK_VIEW])) {
    g_mouse_state.x = 0;
    g_mouse_state.y = 0;
    g_mouse->SetMode(Mouse::MODE_ABSOLUTE);
}

And then inside the STATE handler :

// View rotation
if (getStatePressed(g_ActionButtons[LOCK_VIEW])) {
    g_ViewingContext->yaw(-(float)g_mouse_state.x * deltaTime * g_MouseSensitivity);
    g_ViewingContext->pitch((g_MouseInvertY ? 1 : -1) * (float)g_mouse_state.y * deltaTime * g_MouseSensitivity);
    SetCursorPos(g_mouse_abs_x, g_mouse_abs_y); // <- reset mouse position @ r-clicked position each frame
    g_mouse_state.x = 0;
    g_mouse_state.y = 0;
}
