Hi all, I've recently switched from CMake 2.8.12 to 3.2, full of enthusiasm that header-only libraries would now be better supported through the INTERFACE option/target. However, the support for header-only libraries isn't really great, in particular if you're using an IDE like Visual Studio.
The main problem is that if you define an INTERFACE target, there's no way to specify headers, and they won't show up in IDEs. There's workarounds with a custom target, but that's not really great for example to set dependencies, populate the include directory of the library or to INSTALL the target. Brad King said in this (http://www.cmake.org/Bug/view.php?id=15234) ticket that posting here would be appropriate. I've posted a couple of links to Stackoverflow in the ticket as well - other people have this issue as well and the only way out of it is some hacks, neither of which are satisfactory. I'm sorry if this has been been discussed before, I just joined the list, and I couldn't find any means to search through the mailing list archives (except through Google, whose results didn't indicate it had been discussed before). But even if it has been discussed before, I think it's appropriate to raise this issue again - hopefully, a fix should not be that hard. Thanks, Patrik
