i am facing this issue even though i had installed the OpenSSL 3.1.6 4 Jun 2024 (Library: OpenSSL 3.1.6 4 Jun 2024)

Could not find directory of OpenSSL installation, and this -sys crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the OPENSSL_DIR environment variable for the
compilation process.

Make sure you also have the development packages of openssl installed.
For example, libssl-dev on Ubuntu or openssl-devel on Fedora.

If you're in a situation where you think the directory should be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.

$HOST = x86_64-pc-windows-msvc
$TARGET = x86_64-pc-windows-msvc
openssl-sys = 0.9.102

It looks like you're compiling for MSVC but we couldn't detect an OpenSSL
installation. If there isn't one installed then you can try the rust-openssl
README for more information about how to download precompiled binaries of
OpenSSL:

note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

You need to either set the OPENSSL_DIR environment to point at where you installed OpenSSL or use setup vcpkg to automatically locate it.
