It is still possible to use the 3.0 FIPS module even if you use static
linking to link to libcrypto. However the FIPS module itself is always a
dynamically loaded shared object (i.e. a .so file).
So, you statically link your application to libcrypto.a. When needed
(either as a result of config, or an explicit call to
OSSL_PROVIDER_load()), then the FIPS module fips.so file will be
dynamically loaded at runtime by libcrypto. How libcrypto is linked to
the application does not impact its ability to dynamically load the FIPS
module at runtime.
