@anutosh491 can you give this PR a better title and description? This PR appears to be less about bumping to 5.2.0, but more removing the redundant EXPORTED_RUNTIME_METHODS in xeus-cpp, given its now taken care of by xeus 5.2.0

[anutosh491]

Cool.

Yeah we aren't like "bumping" "bumping" but that's a by product of always fetching the latest xeus.
