A little introduction: cmake is an alternative for autotools, more and more packages are using it (and some new big ones are on the way, KDE4 for example).
I've wrote an eclass that makes writing ebuilds for such packages a little easier - it provides an ecmake function that takes care of few needed variables, prefix and such. I'm open for discussion about it, the eclass currently is only in my overlay at o.g.o. For example I've changed sys-power/ncpufreqd to use the cmake.eclass, complete ebuild can be viewed at http://overlays.gentoo.org/dev/nelchael/browser/sys-power/ncpufreqd/ncpufreqd-2.4.ebuild (compare it to the in-tree version: http://sources.gentoo.org/viewcvs.py/gentoo-x86/sys-power/ncpufreqd/ncpufreqd-2.4.ebuild?rev=1.1&view=markup ) Following ebuilds (52 to be exact) have dev-util/cmake in {R,}DEPEND (so could use the new eclass): app-cdr/cdrkit-1.1.2 app-cdr/cdrkit-1.1.4 app-cdr/cdrkit-1.1.5.1 app-cdr/cdrkit-1.1.6 app-mobilephone/gammu-1.12.0 app-mobilephone/gammu-1.13.0 dev-cpp/eigen-1.0.5 dev-cpp/gccxml-0.6.0-r1 dev-cpp/gccxml-0.7.0_pre20060311 dev-db/mysql-community-5.1.14_beta-r1 dev-db/mysql-community-5.1.15_beta dev-db/mysql-community-5.1.21_beta dev-games/physfs-1.1.1 dev-php5/php-qt-0.1 dev-ruby/qt4-qtruby-1.4.8 dev-ruby/qt4-qtruby-1.4.9 dev-ruby/qt4-qtruby-1.4.9-r1 dev-util/dwarves-1.0_p1 dev-util/kdesvn-0.11.2 dev-util/kdesvn-0.12.1 dev-util/kdesvn-0.13.0 dev-util/kdesvn-0.14.0 games-fps/doomsday-1.9.0_beta5 games-puzzle/ksudoku-0.4 games-strategy/boson-0.13 games-strategy/hedgewars-0.9.0 games-strategy/hedgewars-0.9.0-r1 kde-misc/kbfx-0.4.9.3.1-r1 kde-misc/kgtk-0.9.1-r1 media-libs/libprojectm-1.01 media-libs/libprojectm-1.01-r1 media-plugins/libvisual-projectm-1.0 media-sound/mppenc-1.16 media-sound/musescore-0.6.1 media-sound/musescore-0.7.0.1 media-sound/rosegarden-1.5.1 net-p2p/museek+-0.1.13-r1 sci-astronomy/stellarium-0.9.0 sci-chemistry/avogadro-0.1.0 sci-chemistry/avogadro-0.2.0 sci-geosciences/marble-0.3 sci-geosciences/marble-0.4 sci-libs/vtk-5.0.3 sci-visualization/paraview-2.6.2 sys-apps/initng-0.6.10.1 sys-apps/initng-9999 sys-apps/initng-ifiles-0.1.4 sys-power/ncpufreqd-2.4 x11-themes/gtk-engines-qt-0.7_p20070327-r2 x11-themes/gtk-engines-qt-0.8 x11-themes/gtk-engines-qtcurve-0.55.0 x11-themes/qtcurve-0.55.0 -- Krzysiek Pawlik <nelchael at gentoo.org> key id: 0xBC555551 desktop-misc, desktop-dock, x86, java, apache, ppc...
