wxWidgets-3.0: defunct wx-config

[mojca (Mojca Miklavec)]

I seem to have some issues with wxWidgets recently on macOS 10.13:

$ export WXDEBUG=1
$ /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/bin/wx-config --cxxflags

  input parameters          = 
  libs parameters           = 
  optional-libs parameters  = 
  input options     = 
  yes/no options    = 
  flag options      = 
  output options    = cxxflags
    cxxflags = yes
  query options     = 

  prefix       = '/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0'
  exec_prefix  = '/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0'
  wxconfdir    = '/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/wx/config'
  m_host       = ''
  m_toolkit    = '[^-]+'
  m_widgetset  = '(univ)?'
  m_chartype   = '(unicode|ansi)'
  m_debugtype  = '(debug|release)'
  m_flavour    = '(-[^-]+)?'
  m_version    = '[0-9]+\.[0-9]+'
  m_linkage    = '?(static)?'
  configmask   = '^[^-]+(univ)?-(unicode|ansi)-?(static)?-[0-9]+\.[0-9]+(-[^-]+)?$'
  this config  = 'osx_cocoa-unicode-3.0'

  must delegate to an alternate config
  potential delegates (0):

          Warning: No config found to match: ^[^-]+(univ)?-(unicode|ansi)-?(static)?-[0-9]+\.[0-9]+(-[^-]+)?$
                   in /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/wx/config
          If you require this configuration, please install the desired
          library build.  If this is part of an automated configuration
          test and no other errors occur, you may safely ignore it.
          You may use wx-config --list to see all configs available in
          the default prefix.

$ /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/bin/wx-config --list

  input parameters          = 
  libs parameters           = 
  optional-libs parameters  = 
  input options     = 
  yes/no options    = 
  flag options      = 
  output options    = list
    list = yes
  query options     = 

  prefix       = '/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0'
  exec_prefix  = '/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0'
  wxconfdir    = '/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/wx/config'
  m_host       = ''
  m_toolkit    = '[^-]+'
  m_widgetset  = '(univ)?'
  m_chartype   = '(unicode|ansi)'
  m_debugtype  = '(debug|release)'
  m_flavour    = '(-[^-]+)?'
  m_version    = '[0-9]+\.[0-9]+'
  m_linkage    = '?(static)?'
  configmask   = '^[^-]+(univ)?-(unicode|ansi)-?(static)?-[0-9]+\.[0-9]+(-[^-]+)?$'
  this config  = 'osx_cocoa-unicode-3.0'


    Default config is osx_cocoa-unicode-3.0

          No config found to match: ^[^-]+(univ)?-(unicode|ansi)-?(static)?-[0-9]+\.[0-9]+(-[^-]+)?$
          in /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/wx/config

          Please install the desired library build, or specify a different
          prefix where it may be found.  If the library is not installed
          you may call its wx-config directly by specifying its full path.


  Also available in /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0:
    osx_cocoa-unicode-3.0
