[kea-dev] Boost 1.89 build woes

[Francis Dupont]

The new code which works with all boost versions >= 1.66 in meson.build is:

boost_dep = dependency('boost', version: '>=1.69', required: false)
if not boost_dep.found()
    boost_dep = dependency('boost', version: '>=1.66', modules: ['system'])
endif

Thanks
