Fabrice, All,

Why do you drop this comment?

So, yes, the last part of it is wrong: we won;t whine, but we will build
our own. Otherwise, the comment is still valid, and I prefer a "generic"
comment rather than the name of the affected package.

If onwe wants to check why the version is set to 3.8, one can git-blame
the file, and see the commit log that identifies the culprit package.

Additionally, now that we update the version to 3.8, you may also remove
package/json-for-modern-cpp/0001-buildsystem-relax-requirement-on-cmake-version.patch
