cppcheck warnnings about jwt-cpp HOT 2 CLOSED

I made the constructors of all the algorithms explicit, however I cant do much about the errors in picojson as it is a 3rd party lib and I'd like to avoid modifying it to make updates to it easier.
Apart from this: All of them are "just" style warnings so while its good to fix them its not a dealbreaker.
What version of cppcheck are you using ?
Mine did not say a word about the missing explicits.

from jwt-cpp.

Yes, those are just warnnings, not errors.

Here is my environment
[root@centos1 ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[root@centos1 ~]# cppcheck --version
Cppcheck 1.88
