KDE Core/Platform 11/Buildsystem/FindFilesSurvey

Rationale

One of the "coding" tasks consisted of actually going through our Find*.cmake files in kdelibs and its siblings and check what could be removed, upstreamed or merged in the future.

The following tables look not only at the Find files, but also at some helper CMake files which may also cease to exist or move together with their Find counterparts.

kdelibs, kdepimlibs, kde-baseapps, kde-runtime and kde-workspace were analysed.

By the way, these tables were created using Emacs' org-mode, and there was no easy way to convert them to MediaWiki's syntax :)

Check*.cmake files

File Name	Exists in CMake	Plan	Status	Style	Reviewed
CheckCXXSourceCompiles.cmake	Yes	Search mailing list for CMake developers' rationale, maybe upstream. Began to diverge; CMake has FAIL_REGEX support, our version handles imported targets (Alex said CMake developers did not accept this feature upstream, need to search the mailing list archives).
CheckCXXSourceRuns.cmake	Yes	Idem.
CheckCXXSymbolExists.cmake	No	Either check if we still support glibc 2.9, perhaps try upstreaming. Almost equivalent to CMake's CheckSymbolExists.cmake, just creates .cxx files instead of .c ones.
CheckPointerMember.cmake	No	Only used by krdc; remove from kdelibs? Calls check_cxx_source_compiles on a struct with a given member.
CheckPrototypeExists.cmake	No	1d0e1a0 says this was going to be upstreamed. Try again?
CheckStructMember.cmake	No	Remove; CMake has CheckStructHasMember.cmake

Generic Macros

File Name	Exists in CMake	Plan	Comments	Style	Status	Who
MacroAddCompileFlags.cmake	No	Remove	A trivial macro, used only in few places (kdm mainly I think).	-	Need feedback	-
MacroAddLinkFlags.cmake	No	Remove	A trivial macro, used only in few places (kdm mainly I think).	-	Need feedback	-
MacroAdditionalCleanFiles.cmake	No	Remove	Use set_property(DIRECTORY APPEND PROPERTY ADDITIONAL_MAKE_CLEAN_FILES file1 ... ) instead	-	Decided	-
MacroAppendIf.cmake	No	Remove	Not used anywhere. (Raphael) Really ? (Alex)	Ok	Need feedback	?
MacroBoolTo01.cmake	No	Upstream to ECM		Ok	Need feedback	?
MacroEnsureOutOfSourceBuild.cmake	No	Upstream to ECM or CMake	Many people request something like this on the cmake list.	Ok	Need feedback	?
MacroEnsureVersion.cmake	No	Upstream? to ECM ? Or Remove ?	It doesn't do much more than if(... VERSION_GREATER ...) . This was not available yet in 2007 when the macro was written.	Ok	Need feedback	?
MacroKAuth.cmake	No	Remove. Already deprecated.		-	Decided	-
MacroLibrary.cmake	No	Upstream to ECM	The idea of this file is that it simply includes all macro files so as user you have to include only this one file and get all macro from ECM.	Ok	Need feedback.	?
MacroLogFeature.cmake	No	Remove and extend CMake's FeatureSummary as necessary.	Investigate CMake's FeatureSummary, what needs to be added so that MacroLogFeature becomes unnecessary. This requires some real work.	Ok	Need feedback	?
MacroOptionalAddSubdirectory.cmake	No	Upstream to ECM	Will not be accepted into CMake	Ok	Decided	?
MacroOptionalDependPackage.cmake	No	Remove	Broken, expects a FindFoo.cmake possibly provided by the application itself.	-	Decided	-
MacroOptionalFindPackage.cmake	No	Remove	in CMake 2.8.6 each find_package() call can be disabled via CMAKE_DISABLE_FIND_PACKAGE_PackageName.	-	Decided	-
MacroPushRequiredVars.cmake	No	Upstream to CMake or ECM	Useful when testing for stuff using check_function_exists() etc.	Ok	Decided	Alex
MacroWriteBasicCMakeVersionFile.cmake and BasicFindPackageVersion.cmake.in	No	Upstream to CMake or ECM	Useful for every package which installs a FooConfig.cmake file	Ok	Decided	Alex

Find*.cmake

In this table, "upstreaming" a module can mean sending it to either CMake itself or the external modules collection.
