The cause is rather that the RPATH has not made it into the output
files, so the run-time linker does not know where to find libssl.so.3.
You can use readelf -d or objdump -p + some ELF executable to figure,
example below.

So, sorry for the confusion. I have just taken the time to tweak for
Fedora 35, and I figured that the -Wl,-rpath isn't trivially passed
through, but requires a specific syntax (see NOTES-UNIX.md) to be
recognized and not silently ignored.

For Fedora Linux 35 on amd64, I also figured that the default output
directory would be /opt/openssl3/lib64 (mind the 64).

On Fedora 35, I received a successful build and working install with
(note comma, not assignment/equals, between -Wl,-rpath and the path):

> mkdir _build
> cd _build
> ../config --prefix=/opt/openssl3 -Wl,-rpath,/opt/openssl3/lib64

adjust -j8 to -j followed by the number of availble CPU threads.


This, for me on Fedora 35, yields an openssl that works, with

/opt/openssl3/bin/openssl version -a
/opt/openssl3/bin/openssl s_client -connect fetchmail.sourceforge.io:443
-CAfile /etc/ssl/certs/ca-bundle.trust.crt -verify 5

HTH.

Matthias
