I've looked around and it seems I need to build the package from source but I cannot find the source or figure out how to build it. I downloaded libpcre3-dev_8.39-15_amd64.deb but im not sure what to do with the file.
are you sure the pcre package in Fedora/Nobara doesn't suit your needs?
Debian packagers really likes a lot to complicate packaging for no good reason, splitting the software in different packages like -dev for headers only or somehow getting a "3" in the name despite the software only having pcre and pcre2 with different versions
while other linux packager put the whole software in one single package and call it a day for simplicity sake
