We should have a standard make system that we use for official build instructions etc and in my mind thats where the real debate lies. Even then we could provide multiple instructions. If one make system begins to stand out from the others perhaps it will become default just from user uptake.....</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Regards</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Tim</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR><DIV><DIV>On 07/09/2006, at 15:20, Mateusz Loskot wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Martin Dobias wrote:</DIV> <BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">On 9/7/06, Mateusz Loskot <<A href="mailto:mateusz@loskot.net">mateusz@loskot.net</A>> wrote:</DIV> <BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Martin Dobias wrote:</DIV> <BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Some time ago I've read about CMake build system and that KDE</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">developers have switched from autotools to it for KDE4.
