Vcpkg: CMake: Could NOT find OpenSSL

[Sampalo]

I am trying to get started with _Simple-Web-Server_ over at
https://gitlab.com/eidheim/Simple-Web-Server

vcpkg install openssl:x64-windows

installed_two openssl libraries:

_openssl[core]:x64-windows_
_* openssl-windows[core]:x64-windows_

vcpkg list

lists these

_openssl-windows:x64-windows_
_openssl:x64-windows_

_openssl:x64-windows_ had version number 0 and contained no actual files

Run (windows-button + r) _openssl_

OpenSSL> version
OpenSSL 1.0.2p 14 Aug 2018

enter _Simple-Web-Server\build_ dir and run this command

cmake .. "-DCMAKE_TOOLCHAIN_FILE=D:\vcpkg\scripts\buildsystems\vcpkg.cmake"

produces this error

CMake Error at C:/Program Files/CMake/share/cmake-3.12/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

//The CMake toolchain file

I have tried different openssl version, and even deleting the empty _openssl:x64-windows_

I am using windows 10, with the command prompt for VS 2017
I am not sure if this is a vcpkg, cmake or openssl issue

vcpkg integrate install ?
or
cmake .. -DCMAKE_PREFIX_PATH="D:/vcpkg/installed/x64-windows-static" -DCMAKE_TOOLCHAIN_FILE:FILEPATH="D:/vcpkg/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_CONFIGURATION_TYPES=Release -DBUILD_STATIC=ON -DCMAKE_CL_64=1 -G"Visual Studio 15 2017 Win64"

-DCMAKE_PREFIX_PATH

I forgot to write it,
I did

vcpkg integrate install

it said it was successful

[Voskrese]

set OPENSSL_ROOT_DIR="D:/vcpkg/installed/x64-windows-static"
cmake .. -DOPENSSL_ROOT_DIR="D:/vcpkg/installed/x64-windows-static" ...

[Sampalo]

ok thanks, I will try the new cmake commands
I am not currently close to a machine that I can try this on. I will try tomorrow

[Sampalo]

wow thanks a lot!
adding -DOPENSSL_ROOT_DIR="D:/vcpkg/installed/x64-windows-static"
worked like a charm!

Had the same problem, -DVCPKG_TARGET_TRIPLET=x64-windows-static did the trick.

Thanks guys. I got a similar issue though my environment is slightly different as my MSVC, vcpkg, OpenSSL are all the latest versions. I fixed it by adding -DOPENSSL_ROOT_DIR="C:/vcpkg/installed/x64-windows-static":
