[Buildroot] [PATCH 1/1] package/capnproto: add openssl optional dependency

[Yann E. MORIN]

Fabrice, All,

On 2020-07-27 14:41 +0200, Fabrice Fontaine spake thusly:
> openssl is an optional dependency that is enabled by default since
> version 0.7.0 and
> https://github.com/capnproto/capnproto/commit/23db5e3fd91104a0b2881d8f8ab3c10bf9dd8e75

Seeing how they are testing for openssl, will that no fail for a staitc
link, because they forget to link with -lz in that case ?

      AC_CHECK_LIB(ssl, OPENSSL_init_ssl, [:], [
        with_openssl=no
      ], [-lcrypto])

Why don't they yse pkg-config?

Additionally/alternatively, they do have a cmake-based buildsystem. Can
we switch over?

Regards,
Yann E. MORIN.
