We will still be able to generate the autodocs ( make docs), but only in-place, and they won't be installed.Īs a matter of fact, CMake has very good and easy-to-use support for generating autodocs, but no support at all to install them to the system this seems to be a very clear indication that this is something very uncommon. Get rid of the -doc subpackages they only contain doxygen-generated autodocs of limited use. Submit all subpackages at once to OBS ( to be discussed).changes files into a single one? ( to be discussed) (Hopefully) use one common VERSION.cmake file for all subpackages.(Hopefully) keep package version numbers in sync ( to be discussed).Build each subpackage from one large tarball containing that complete merged repo.Merge all SUSE-maintained libyui Git repos into one is working on that).Include( GNUInstallDirs ) # set CMAKE_INSTALL_INCLUDEDIR.

# CMakeLists.txt for libyui/src include(. Keep it simple is the (new) principle here. No more PROJECTINFO.cmake or SOURCELIST.cmake, no magic locating of libs and headers that we need here from some faraway place. cmake files one directory level above (!). Unlike the previous build system, this is complete and self-contained no hidden magic, no voodoo, no collecting tidbits of information from "magic places" like all those tiny.

For example, to build without examples/, you would invoke cmake like this: There is a separate command line option for each subdirectory to configure whether or not this subdirectory should be built. This file contains some options that can be set on the cmake command line, some global definitions, and it descends into subdirectories. # We need this because we have a subdirectory doc/, a subdirectory package/ # and possibly a subdirectory build/ here.PHONY: doc package build Toplevel CMakeLists.txt # Enforce rebuilding some targets unconditionally, even if a file or directory # with that name exists otherwise the timestamp of that file or directory # would be checked. # Just an alias bump-version: version-bump Make -j $$( nproc) # This needs root privileges, of course install: configure # Makefile.repo for libyui # Local Variables: # mode: Makefile # End: all: clean configure " "To build: " " cd build " make " " configure:

But with this file, you don't need to guess what to do and how to do it. It's only convenience you can easily do all those operations completely manually. This is the starting point for most operations.

Toplevel Makefile.repo as a starting point and reminder how things work.cmake files that are unclear what they are and where they are filled with content, yet needed in hand-written. cmake files that do magic things, are hard to read and understand, almost impossible to change because they are so convoluted, and completely out of date since CMake improved a lot over all those years. cmake files with bits and pieces of information Enough in-line documentation to get started even with very little CMake know-how.Self-sufficient no external files needed.The New (2021/01) CMake Build System for Libyui
