Can you share the output you see for:
$ export PKG_CONFIG_PATH=/usr/openssl/3/lib/64/pkgconfig
$ pkg-config --cflags --libs libssl libcrypto
For comparison, my build of OpenSSL 3.2 beta from stock upstream sources
(with a custom --prefix) yields:
$ export PKG_CONFIG_PATH=/usr/local/siteexec/lib/pkgconfig
$ pkg-config --cflags libssl libcrypto
-I/usr/local/siteexec/include
$ pkg-config --libs libssl libcrypto
-L/usr/local/siteexec/lib -lssl -lcrypto

I would have tried instead:
PKG_CONFIG_PATH=/usr/openssl/3/lib/64/pkgconfig \
make makefiles dynamicmaps=yes shared=yes \
openssl_path="/usr/openssl/3/bin/openssl" \
CC="/usr/bin/gcc -m64" \
CCARGS="-DUSE_DB -DUSE_TLS $(pkg-config --cflags libssl libcrypto)" \
AUXLIBS="-ldb $(pkg-config --libs libssl libcrypto)" \
but, you may still also need an explicit "-R/usr/openssl/3/lib" option,
if that's not part of what "pkg-config" returns for "--libs".
