I download and compile openssl 3.0.2 from source and want to link it
with libcurl on macOS, however, I encounter some issues, I use latest
libcurl 7.82.0.
below is configure.

./configure --prefix="$(pwd)/curl"
--with-ssl=/Users/test/Downloads/openssl-openssl-3.0.2/openssl
--enable-static --disable-shared --disable-ftp --disable-file
--disable-ldap --disable-dict --disable-telnet --disable-tftp
--disable-rtsp --disable-pop3 --disable-imap --disable-smtp
--disable-gopher --disable-ares --disable-debug
--with-zlib=/Users/test/Downloads/zlib-1.2.11/zlib --without-libidn
--without-brotli --without-zstd --without-nghttp2 --without-librtmp
--without-libidn2 --without-winidn

Host setup: x86_64-apple-darwin20.6.0
  Install prefix: /Users/test/Downloads/curl-7.82.0/curl
  Compiler: gcc
   CFLAGS: -Qunused-arguments -Wno-pointer-bool-conversion
-Os -Werror=partial-availability -pthread
   CPPFLAGS: -isystem
/Users/test/Downloads/zlib-1.2.11/zlib/include -isystem
/Users/test/Downloads/openssl-openssl-3.0.2/openssl/include
-DOPENSSL_SUPPRESS_DEPRECATED
   LDFLAGS: -framework CoreFoundation -framework
SystemConfiguration -L/Users/test/Downloads/zlib-1.2.11/zlib/lib
-L/Users/test/Downloads/openssl-openssl-3.0.2/openssl/lib
   LIBS: -lssl -lcrypto -lssl -lcrypto -lz

  curl version: 7.82.0
  SSL: enabled (OpenSSL v3+)

But when make, it will output error:

Undefined symbols for architecture x86_64:
  "_EVP_PKEY_id", referenced from:
      _ossl_connect_common in libcurl.a(libcurl_la-openssl.o)
  "_SSL_get_peer_certificate", referenced from:
      _ossl_connect_common in libcurl.a(libcurl_la-openssl.o)
ld: symbol(s) not found for architecture x86_64

Test: I found my macOS installed openssl at /usr/local/include/openssl
which is 1.1.1m, After I remove this folder, The error is fixed. So I
think the system installed openssl header is affected in libcurl make.

I think I have configured libcurl to use
/Users/test/Downloads/openssl-openssl-3.0.2/openssl/include, but it
does not work.

How can I fix this?
