By this I mean use set_property() or set_target_properties() rather than target_include_directories() or include_directories(). Note, however, that the documentation for the INCLUDE_DIRECTORIES property explicitly recommends against adding relative paths to the property like this (but in your case it sounds like you really want a relative path, so maybe this is a valid exception to that advice).<div><br><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Mon, Oct 17, 2016 at 9:46 AM, Steve Lorimer <span dir="ltr"><<a href="mailto:steve.lorimer@gmail.com" target="_blank">steve.lorimer@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr">In makefile parlance, I'm trying to add -I.
