cmake error regarding openssl

[David List]

When running cmake on mysql source, it fails with the last few lines saying this:

-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR)
-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR)
--
Could not find system OpenSSL
Make sure you have specified a supported SSL version.
Valid options are :
openssl[0-9]+ (use alternative system library)
yes (synonym for system)
</path/to/custom/openssl/installation>

I have tried every option for -DWITH_SSL=[option] I can think of, and am at my wits end. I hope someone here can suggest a solution.

I am trying to install mysql-8.4.4.
"openssl version" gives me "OpenSSL 3.4.1 11 Feb 2025 (Library: OpenSSL 3.4.1 11 Feb 2025)"
"cmake --version" gives me "cmake version 4.0.0-rc4"
