Subject: [Tarantool-patches] [PATCH luajit 2/5] build: replace GNU Make with CMake
Date: Tue,  2 Feb 2021 23:57:42 +0300
Message-ID: <7cd42be38d86c832ecd4ba0f3edd7ae83aead7ad.1612291495.git.imun@tarantool.org> (raw)
In-Reply-To: <cover.1612291495.git.imun@tarantool.org>

In scope of this patch the LuaJIT build system is partially ported from
GNU Make to CMake. These changes provides CMake build system only for
the following OS: GNU/Linux, OSX, FreeBSD. For other platrforms use the
old build system (see the recipe in the previous commit).

Several components of the new build system such as automatic version
detection, source files list generation and some recipes for
CMakeLists.txt are taken verbatim or adapted from LuaVela repository.

Part of tarantool/tarantool#4862

Signed-off-by: Igor Munkin <imun@tarantool.org>
