So I checked and realised we actually gotten rid of those INTERFACE libraries, because we encountered all kinds of trouble, amongst which one is the problem you refer to. Another problem for instance, is that INTERFACE link dependencies don’t get transferred like with normal libraries. Extremely annoying, so we decided the ‘academical’ use of an INTERFACE library wasn’t (nearly) worth the effort.</div><div class=""><br class=""></div><div class="">Not a resolution to your problem though ……</div><div class=""><br class=""></div><div class="">Sincerely, Jakob</div><div class=""><br class=""></div><br class=""><div><blockquote type="cite" class=""><div class="">On 02 Jan 2016, at 13:12, Klaim - Joël Lamotte <<a href="mailto:mjklaim@gmail.com" class="">mjklaim@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><br class="Apple-interchange-newline"><br style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><div class="gmail_quote" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">On 1 January 2016 at 11:00, Jakob van Bethlehem<span class="Apple-converted-space"> </span><span dir="ltr" class=""><<a href="mailto:jsvanbethlehem@gmail.com" target="_blank" class="">jsvanbethlehem@gmail.com</a>></span><span class="Apple-converted-space"> </span>wrote:<br class=""><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left-width: 1px; border-left-color: rgb(204, 204, 204); border-left-style: solid; padding-left: 1ex;"><div style="word-wrap: break-word;" class=""><div class="">Hej Joël,</div><div class=""><br class=""></div><div class="">The command you’re looking for is ‘source_group’, see <a href="https://cmake.org/cmake/help/v3.0/command/source_group.html" target="_blank" class="">https://cmake.org/cmake/help/v3.0/command/source_group.html</a></div><div class=""><br class=""></div></div></blockquote><div class=""><br class=""></div><div class="">I use this already but it works only with source files, not with targets.
