  # The first two patches are taken from the debian packaging of tinyxml.
  #   The first patch enforces use of stl strings, rather than a custom string type.
  #   The second patch is a fix for incorrect encoding of elements with special characters
  #   originally posted at https://sourceforge.net/p/tinyxml/patches/51/
  # The third patch adds a CMakeLists.txt file to build a shared library and provide an install target
  #   submitted upstream as https://sourceforge.net/p/tinyxml/patches/66/
