Support for embedding data in a manner equivalent to xxd

FWIW, it’s possible to implement this purely in CMake, based on the string(HEX) command. This works for me:

function(xxd outVar text)
  string(HEX "${text}" hex)
  string(LENGTH ${hex} hexLen)
  math(EXPR hexLen "${hexLen} - 1")
  set(result "")
  foreach(idx RANGE 0 ${hexLen} 2)
    string(SUBSTRING ${hex} ${idx} 2 char)
    list(APPEND result "0x${char}")
  endforeach()
  list(JOIN result ", " result)
  set(${outVar} ${result} PARENT_SCOPE)
endfunction()
