He did various fixes, so I think that fixing this in the proper way (which I can't help to, sorry) would be good.</pre>

Which is why my patch is Mac-specific.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">But frankly, I don't see the point in obliging each and every dependent project to declare the minimum required cmake version. Not if that's not a requirement of cmake itself, nor of the project, but of one of the libraries it uses. I really don't see how this is different from, say, declaring CMake macros that are specific to KDE and not to a given dependent project.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">On the contrary, it seems clear that the version requirement stems from something done in (or included by) a cmake file that's installed through kdelibs. In my book that makes it kdelibs' responsibility to declare the minimum required version. If it's not yet set, and/or as long as subsequent calls to <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">cmake_minimum_required</code> do not override (= downgrade) minimum versions set by preceding calls.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">That said, I'm going to have to get back to my Mac to verify why I apparently missed kdepim commit 8a187bc316271caed9c2591d91fb8706abe5c665 ("Fix the build after yet another cmake policy change") or what else is going on.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It is a requirement of cmake itself, and it has been for 6 years.</p></pre>
