[Tarantool-patches] [PATCH luajit] cmake: fix warnings about minimum required version

[Sergey Bronnikov via Tarantool-patches]

From: Sergey Bronnikov <sergeyb@tarantool.org>

CMake produces annoying warnings:

CMake Deprecation Warning at src/CMakeLists.txt:7 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

We cannot bump a minimum required CMake version without
bumping it in a Tarantool build system. However, we can set
a max supported CMake version and suppress a warning.
CMake 3.27.7 is a version used by me for a long time for
building LuaJIT. This version is tested and seen no policy warnings
with a that version.

NOTE: another solution is using CMAKE_WARN_DEPRECATED,
but I don't like it. Let's discuss.

Please specify in the commit message and in comments in cmake files
that maximum supported version means "maximum version this CMake file
is known to work properly" and will not result in any build errors
rightaway for higher versions.

Hi, Sergey!
Thanks for the fixes!
LGTM now.

Re: [Tarantool-patches] [PATCH luajit] cmake: fix warnings about minimum required version

[Sergey Kaplun via Tarantool-patches]

Hi, Sergey!
Thanks for the patch!
Generally LGTM, but I have a couple of questions:

1) What happens if we use a feature that is introduced in 2.4 (for
example) and becomes deprecated in:
a) 2.27?
b) 2.30?

2) Can we declare the minimum required version in the root
CMakeLists.txt of the project instead?

Re: [Tarantool-patches] [PATCH luajit] cmake: fix warnings about minimum required version

Hi, Sergey

According to CMake documentation: [1]

 > *All policies known to the running version of CMake and introduced in 
the <min> (or <max>, if specified) version or earlier will be set to use 
NEW behavior. All policies introduced in later versions will be unset.* 
This effectively requests behavior preferred as of a given CMake version 
and tells newer CMake versions to warn about their new policies.

Looks acceptable for us, right?

Also, I've updated a comment before cmake_minimum_required:

and added a note to the commit message regarding compatibility

with Tarantool's cmake minimum required version:

   Note, that a current minimum required version in Tarantool is equal
     to 2.8, but <policy_max> is introduced in CMake 3.12 [2].
     However, according to [2] it is not a problem, because if CMake is
     "older than 3.12, the extra ... dots will be seen as version
     component separators, resulting in the ...<max> part being ignored
     and preserving the pre-3.12 behavior of basing policies on <min>".

It is already done in the branch, but I haven't sent an updated

version to the list. Sorry, my bad. I'll send v2 soon.

Sergey,

I've checked the patchset into all long-term branches in
tarantool/luajit and bumped a new version in master [1], release/3.1 [2]
and release/2.11 [3].

[1]: https://github.com/tarantool/tarantool/pull/10200
[2]: https://github.com/tarantool/tarantool/pull/10201
[3]: https://github.com/tarantool/tarantool/pull/10202
