The FreeType license is similar to BSD *plus* an advertising clause.

This is explicitly described in the license text, `FTL.TXT', for
example

  Portions of this software are copyright ©2017 The FreeType Project
  (www.freetype.org).  All rights reserved.

This is also explicitly described in the license text...

  We suggest, but do not require, that you use one or more of the
  following phrases to refer to this software in your documentation or
  advertising materials: `FreeType Project', `FreeType Engine',
  `FreeType library', or `FreeType Distribution'.

In other words, it's sufficient to mention FreeType in your
documentation.
