Hello! 28.12.2020, 07:03, "Bruno Haible" <bruno@clisp.org>: I propose to merge CMake build branch [1] into CLN [1] https://github.com/asheplyakov/cln/tree/cmake I've been using it to build CLN and GiNaC for a long time (since 2010 or so) both for Linux and Windows (MinGW).
It seems that using a CMake 'ExternalProject' would allow you to use CLN's configure-based build system from CMake [1]. No?
ExternalProject does *not* provide any integration. One has to manually define lots of preprocessor, compiler, linker flags both for ExternalProject itself and the code which uses it. With CMake all of these is a matter of target_link_library(myprogram PRIVATE cln::cln) This becomes very tedious if the program needs several external projects.
It is usually a waste of time to maintain two build systems (for CLN, in this case) in parallel, when one is sufficient.
I disagree. Firstly I don't think autotools based build is sufficient: a) Generating a correct configure script is rather nontrivial (sort of plug and pray) b) No integration with IDEs c) Building on Windows is a pain Secondly *maintaining* two build systems is not that bad. Especially when it's someone else (for instance me) who does the maintenance. Best regards, Alexey
