[Buildroot] [PATCH v1] libinput: drop C++ dependency

[Yann E. MORIN <yann.morin.1998@free.fr>]

Peter, All,

On 2019-01-12 00:01 +0100, Peter Seiderer spake thusly:
> The meson C++ dependency is only used for a build-time header
> include test, so drop both.

You may want to test something like that:

    if add_languages('cpp')
        executable('test-build-cxx',
            blablabla)
    endif

If that works, then I think I'd prefer we use this patch, because it is
upstreamable, which you should try to do btw.

Yann E. MORIN.
