You *may* use GPL code in your own code in-house without releasing it under
the GPL. You must *only* release your product under the GPL if you
distribute it to the public in binary form (Section 2).
The LGPL is more permissive than the GPL, allowing you to link with it

You *may* reuse LGPL code in a proprietary product in-house, as with the

code, provided you give "prominent notice" that you're using LGPL code and
offer to redistribute any modifications you've made to the LGPL code
