Nathan Lanza a7626e13c1 [cmake] Only set deps for an ExternalProject if the type is executable or library 
Summary:
cmake fails with an error when attempting to evaluate $<TARGET_FILE:tgt>
where `tgt` is defined via an `add_custom_target` and thus the `TYPE`
is `UTILITY`. Requesting a TARGET_FILE only works on an `EXECUTABLE`
or one of a few differetnt types of `X_LIBRARY` (e.g. added via
`add_library` or `add_executable`). The logic as implemented in cmake
is below:

  enum TargetType
  {
    EXECUTABLE,
    STATIC_LIBRARY,
    SHARED_LIBRARY,
    MODULE_LIBRARY,
    OBJECT_LIBRARY,
    UTILITY,
    GLOBAL_TARGET,
    INTERFACE_LIBRARY,
    UNKNOWN_LIBRARY
  };

  if (target->GetType() >= cmStateEnums::OBJECT_LIBRARY &&
      target->GetType() != cmStateEnums::UNKNOWN_LIBRARY) {
    ::reportError(context, content->GetOriginalExpression(),
                  "Target \"" + name +
                    "\" is not an executable or library.");
    return nullptr;
  }

This has always been the case back to at least 3.12 (furthest I
checked) but this is causing a new failure in cmake 3.17 while
evaluating ExternalProjectAdd.
