cmake build warning on linux

[pbertin-oneex]

Hello @antelle,

building on linux (20.04) with cmake v3.16.3 and emcc v2.0.32, I have this warning:

emcc: warning: EXTRA_EXPORTED_RUNTIME_METHODS is deprecated, please use EXPORTED_RUNTIME_METHODS instead [-Wdeprecated]

I'll make a PR with the little change if you are ok with that. 👍

Hi! Indeed you can change it, or I'll do it when it becomes an error.

Thanks @antelle !
