fanquake 7bf04e358a build: remove mostly pointless BOOST_PROCESS macro ... Performing a series of link checks for a Boost component that is header-only doesn't make much sense, and currently means we just have another confusing Boost macro in our tree. I'm not sure why this was originally done this way; maybe Sjors or luke-jr can elaborate (#15382 (929cda5470))? The macro also has the side-effect of producing confusing error messages. i.e in #20744, the CI is currently failing with: ```bash checking for boostlib >= 1.58.0 (105800) lib path in "/tmp/cirrus-ci-build/depends/x86_64-pc-linux-gnu/lib"... yes checking for boostlib >= 1.58.0 (105800)... yes checking whether the Boost::Process library is available... yes configure: error: Could not find a version of the Boost::Process library! ``` This isn't useful, given there is no such thing as a `Boost::Process` library. This PR just removes the macro entirely, but maintains a `--with-boost-process` (defaulting to off), flag to configure. Hopefully this will also be removed, in favour of `--enable-disable-external-signer` if/when #16546 is merged.		2021-02-17 08:04:11 +08:00
