Hi!

I'm a rust beginner trying to install cargo-leptos. I've installed cargo-leptos before, but I'm reinstalling it on a different device and I'm running into some difficulty.

I've installed openssl through Chocolatey, and these are my openssl related environment variables:

OPENSSL_CONF="C:\Program Files\OpenSSL-Win64\bin\openssl.cfg"
OPENSSL_INCLUDE_DIR="C:\Program Files\OpenSSL-Win64\include"
OPENSSL_LIB_DIR="C:\Program Files\OpenSSL-Win64\lib\VC\x64\MD"
OPENSSL_NO_VENDOR="1"

With these environment variables, I get an error like

OpenSSL libdir at ["C:\Program Files\OpenSSL-Win64\lib\VC\x64\MD"] does not contain the required files to either statically or dynamically link OpenSSL

When I set OPENSSL_STATIC="1", the error changes to

could not find native static library ssl, perhaps an -L flag is missing?

What am I doing wrong?
Could someone help me please?
Thanks in advance!

P. S.

I used this link as a reference, and from what I remembered from the last time I installed cargo-leptos, it worked. Now, it doesn't. Maybe I missed something?

`cargo build` fails on my Windows 10 as openssl could not be found. However, it …is installed in `c:\Program Files\OpenSSL-Win64`. The Distributor is http://slproweb.com/products/Win32OpenSSL.html. If only installations installed using vcpkg are supported, could you mention this in the docs? Thanks and thanks for great crate! Bernd My system info is: ``` $HOST = x86_64-pc-windows-msvc $TARGET = x86_64-pc-windows-msvc openssl-sys = 0.9.67 ``` The command output is: ``` λ cargo build Compiling openssl-sys v0.9.67 Compiling atty v0.2.14 Compiling clap v2.33.3 error: failed to run custom build command for `openssl-sys v0.9.67` Caused by: process didn't exit successfully: `c:\Users\krietens\Projects\rust-openssl\target\debug\build\openssl-sys-9a902e1719db51b3\build-script-main` (exit code: 101) --- stdout cargo:rustc-cfg=const_fn cargo:rerun-if-env-changed=X86_64_PC_WINDOWS_MSVC_OPENSSL_LIB_DIR X86_64_PC_WINDOWS_MSVC_OPENSSL_LIB_DIR unset cargo:rerun-if-env-changed=OPENSSL_LIB_DIR OPENSSL_LIB_DIR unset cargo:rerun-if-env-changed=X86_64_PC_WINDOWS_MSVC_OPENSSL_INCLUDE_DIR X86_64_PC_WINDOWS_MSVC_OPENSSL_INCLUDE_DIR unset cargo:rerun-if-env-changed=OPENSSL_INCLUDE_DIR OPENSSL_INCLUDE_DIR unset cargo:rerun-if-env-changed=X86_64_PC_WINDOWS_MSVC_OPENSSL_DIR X86_64_PC_WINDOWS_MSVC_OPENSSL_DIR unset cargo:rerun-if-env-changed=OPENSSL_DIR OPENSSL_DIR unset note: vcpkg did not find openssl: Could not look up details of packages in vcpkg tree could not read status file updates dir: Das System kann den angegebenen Pfad nicht finden.

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 = 0.9.67 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: https://github.com/sfackler/rust-openssl#windows ', C:\Users\krietens\.cargo\registry\src\github.com-1ecc6299db9ec823\openssl-sys-0.9.67\build\find_normal.rs:174:5 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace warning: build failed, waiting for other jobs to finish... error: build failed ``` Note: The URL in the output (https://github.com/sfackler/rust-openssl#windows) is not valid any more!
