compilation/linkage question (static executable with provider functions)

i have openssl-3.1.2, QAT_Engine-1.3.1.
when i compile my program statically , i add all qat_*.o files from the Engine directory, and then get linkage errors,
such as qat_prov_ctx_set_core_bio_method multiple defined.

indeed there are 2 places:
./engines/QAT_Engine-1.3.1/qat_prov_bio.c:224: BIO *ossl_bio_new_from_core_bio(QAT_PROV_CTX *provctx, OSSL_CORE_BIO *corebio)
and
./providers/common/bio_prov.c:226: BIO *ossl_bio_new_from_core_bio(PROV_CTX *provctx, OSSL_CORE_BIO *corebio)

please advise, why the same name of function is used again, and may we link all these files together to get statically build executable with provider code?

thank you!
