CURL does not show all OPENSSL engines on Linux

Question

When I run

bash-4.2# openssl engine
(rdrand) Intel RDRAND engine
(dynamic) Dynamic engine loading support
(pkcs11) pkcs11 engine

But when I run

bash-4.2# OPENSSL_CONF=/etc/pki/tls/openssl.cnf curl --engine list
Build-time engines:
  rdrand
  dynamic 

• I am using Amazon Linux 2 to build curl and libcurl 8.2.1 using openssl 1.1.1g. But despite my efforts to get to list all the OpenSSL engines, I cannot get it to work.
• I have looked at curl/lib/vtls/openssl.c 1705 and tried to add more init flags like OPENSSL_INIT_ENGINE_OPENSSL but to no avail. Please assist me in this.

I am trying to get CURL to list all the OpenSSL engines. And despite my efforts to make CURL souce code work to list all of the engines, I could not.

I was expecting to get all the engines but setting the config file correctly and building curl with openssl.

I am not sure but I do have a preinstalled version of curl that I cannot remove.

And to confirm that I am running the the correct version of curl, I did explicitly launch it and it reported the following:

bash-4.2# ./curl --version
curl 8.2.1-DEV (Linux) libcurl/8.0.1 OpenSSL/1.0.2k-fips zlib/1.2.7 libidn2/2.3.0 libssh2/1.4.3 nghttp2/1.41.0

WARNING: curl and libcurl versions do not match. Functionality may be affected.

I am not sure how to proceed.
