I am assuming that you are referring to the "libertine" font family, and
not the "Liberation" font family.

The "Libertine" font family is dual licensed, available under either the
terms of the GPL with font exception or the OFL.

Now, based on what you've said above, I'm assuming that you would like
to embed the font into the application, and not simply bundle the font
as a separate file to be installed along with the application. At the
same time, you do not want the application to be affected by the GPL
license of the font.

It is my opinion (and IANAL) that the the GPL font exception would not
cover that use case. The OFL seems to be more permissive in this manner,
but I think that the application would need to be compatible with the
OFL licensing (and should you decide to go down that road, you should
retain counsel to determine whether or not that possibility is feasible).

A much cleaner solution would be to bundle the font along with the
application (and install it on the target systems), and use it under the
terms of the OFL.

Specifically, Question 1.5.

Hope that helps,
