KDE Core/Platform 11/Buildsystem/FindFilesSurvey

From KDE Community Wiki

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 Comments Status
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. 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

Find*.cmake

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