how to programmatically specify the path of fipsmodule.cnf and load it in application without using openssl.cnf in OpenSSL 3.0

[Zhongyan Wang]

Hi team,
Do you know how to programmatically specify the path of fipsmodule.cnf and load it in application without using openssl.cnf in OpenSSL 3.0?
Historically, my product uses customized OpenSSL and doesn't have an openssl.cnf.
I need to use FIPS module, and I try to load it, it fails until I specify the fipsmodule.cnf path in openssl.cnf. openssl.cnf is generated when make install, and fipsmodule.cnf is generated by openssl fipsinstall command.
