This is my personal interpreation about the difference between LGPL and BSD License:
LGPL is more strict and requires that the user can rebuild the complete project which makes use of the LGPL Software. It must be possible to rebuild the complete project with an updated version of the LGPL part. In the case where your complete software is available on github or similar platforms, than this difference does not matter.
However you need to inform the user about the different parts and licenses of your software.
For example, have a look at the u8glib license: Google Code Archive - Long-term storage for Google Code Project Hosting.
U8glib does not have a single license. Each font might have a different license with different requirerments.
Depending on the font, which are used in your project, you might need to give proper reference.
