There was a problem hiding this comment. Do we need to set this policy if we force the cmake version to There was a problem hiding this comment. I'll create a ticket, we got some relative paths and somewhere using source dir variable. I recall we added this long time ago to suppress Cmake warning. We'll test with the current code base, to check if this can be removed. |
