Primary purpose is to change C++ version to 17 (from 11). Incidental changes include:

  • moving fmt into included dependency in third_party directory,
  • updating ITK to 5.4.7,
  • fixing zlib issue with dependencies in example build scripts by including zlib build,
  • changing uses of boost optional, any and variant to std versions.
