FreeType license violation!

[V10lator]

libgui includes FreeType. This is the FreeType license: https://directory.fsf.org/wiki/License:FreeType

The important part:

If you use it, or  only parts of it,  in a program,  you must acknowledge somewhere  in  your  documentation  that  you  have  used  the FreeType code. (`credits')

So you might want to add FreeType to the credits section of README.md. See also:

Finally,  many  people  asked  us  for  a  preferred  form  for  a credit/disclaimer to use in compliance with this license.  We thus encourage you to use the following text:

   """  
    Portions of this software are copyright © <year> The FreeType
    Project (www.freetype.org).  All rights reserved.
   """

Please replace <year> with the value from the FreeType version you actually use.

    o Redistribution in binary form must provide a  disclaimer  that
      states  that  the software is based in part of the work of the
      FreeType Team,  in  the  distribution  documentation.  We also
      encourage you to put an URL to the FreeType web page  in  your
      documentation, though this isn't mandatory.

  These conditions  apply to any  software derived from or  based on
  the FreeType Project,  not just the unmodified files.   If you use
  our work, you  must acknowledge us.

  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'.

  As  you have  not signed  this license,  you are  not  required to
  accept  it.   However,  as  the FreeType  Project  is  copyrighted
  material, only  this license, or  another one contracted  with the
  authors, grants you  the right to use, distribute,  and modify it.
  Therefore,  by  using,  distributing,  or modifying  the  FreeType
  Project, you indicate that you understand and accept all the terms
  of this license.
