variables for cross-platform code?

There’s no obvious direction that I should go look up the ENVIRONMENT_MODIFICATION test property (not everyone is reading the HTML docs).

Ah, the link is dropped from the --help docs . Can you file an issue to improve wording to at least encourage looking there?

@dabrahams

So would that get me out of having to use an escaped semicolon in this example?

Yes, semicolon quoting test properties through a generic API was the straw that finally made me say “bah, I just need to implement this in cmake -E env”. .

Note that:

cmake -E env --modify \
  PATH=path_list_prepend:path1 \
  PATH=path_list_prepend:path2

works as you expect (path2:path1:$PATH) so that you can build these up piecemeal instead of having to collate them ahead of time (sorting may be required though).
