CMake Required Features and Migration Epic

Forewords

Roughly this epic is about CMake upstream contributions we need done, and the tooling around that to allow our developers to build the whole lot with a single command and to produce different granularity of tarballs for our downstreams.

Definition of Done

• kde-frameworks-devel has been warned about CMake API changes introduced by the feature

Backlog

Status	Description	Contact
DONE	Upstream automoc into cmake. Done since 2.8.6.	Alex Neundorf
DONE	Extend FeatureSummary.cmake to make MacroLogFeature.cmake unnecessary. Done since 2.8.6.	Alex Neundorf
DONE	Merge MacroOptionalFindPackage.cmake in CMake. find_apckage() has been extended with 2.8.6 so that this is not necessary anymore.	Alex Neundorf
DONE	Create project extra-cmake-modules for distributing additional Find-modules	Alex Neundorf
DONE	Sync our Find-modules from kdelibs/cmake/modules/ with the ones in CMake. Done with CMake 2.8.7	Alex Neundorf
DONE	Merge or make unnecessary a whole bunch of macros from kdelibs/cmake/modules/. Mostly done. Details see KDE_Core/Platform_11/Buildsystem/FindFilesSurvey	Alex Neundorf, Stephen Kelly
TO DO	superbuilds	??	<{{{3}}}>
TO DO	Developers are also affected by the splits. Makes building more tedious. Figure out what to do about this	??	<{{{3}}}>
TO DO	Review the Find-modules in kdelibs (over 100), and find out which ones are currently needed in the frameworks branch. Here is an overview over the current state: http://community.kde.org/KDE_Core/Platform_11/Buildsystem/FindFilesSurvey	??	<{{{3}}}>
TO DO	develop a future-proof mechanism for providing modules additional to cmake in extra-cmake-modules, i.e. so that using projects can decide which additional stuff they want to use, use some things maybe only for some versions of cmake, etc.	??	<{{{3}}}>
TO DO	come to a decision how to deal with pkg-config under Windows (and OSX ?)	??	<{{{3}}}>
TO DO	figure out how to define the default library install dir, taking Debian multiarch into account	??	<{{{3}}}>
TO DO	Figure out how to deal with the install dirs in general: use GNUInstallDirs.cmake coming with cmake ? keep the support for "if I install to the same prefix as kdelibs (...what is kdelibs then ?), I want the same set of install dir",	??	<{{{3}}}>
TO DO	improve the example in kdeexamples/buildsystem/HowToInstallALibrary/, so it can serve as reference	??	<{{{3}}}>
TO DO	somebody has to do the actual porting. Back in the KDE3->KDE4 days Laurent Montel did most of this work. Here is a (hopefully) complete list of changes: http://techbase.kde.org/Development/ECM_SourceIncompatChanges	??	<{{{3}}}>
TO DO	It would be nice if we could get Windows and OSX developers more actively involved with KF5.	Kevin Ottens	<{{{3}}}>
