For EVP_PKEY_id, the OpenSSL man page says
(https://www.openssl.org/docs/man3.0/man3/EVP_PKEY_id.html):

<SNIP>
The EVP_PKEY_id() and EVP_PKEY_base_id() functions were renamed to
include get in their names in OpenSSL 3.0, respectively. The old names
are kept as non-deprecated alias macros.
</SNIP>

It sounds like you are not compiling against OpenSSL 3.0. You are
compiling against an older OpenSSL that provides the symbol
EVP_PKEY_id, and not the newer OpenSSL that provides the symbol
EVP_PKEY_get_id (with EVP_PKEY_id supplied as a #define).

Please zip cURL's config.log, and attach it to the thread.
