    There are two options. Either it can link dynamically with a system
    libpcre2-8.so or statically with pcre2 compiled from source, that was
    downloaded by cmake during the build.

Yup.  I see that.  However we run on an embedded Linux, and our platform
team won't want to add a new library for just one application.  In the
short term, I'll need to build it just for MariaDB myself.  But,
for security and data integrity reasons we can't pull it from the 
internet at build time.  Can the MariaDB pcre2 build process be given
an alternate URL or file path from which to retrieve the pcre2 source
tarball?

    No, it's not possible. It shouldn't be difficult to implement it,
    but at the moment it's not supported.

I saw this upon looking, thank you for clarifying.
