问题
I'm trying to setup a development environment for C++ to compile under Linux x64 using CMake integration with VS2017. To better manage dependencies I choose to use Conan but I'm pretty new to this software and I'm wondering what's the best way to have VS2017 to recognize the dependencies of the project.
For example, I've used Conan to install the POCO library for C++ but when I open the Main.cpp file it doesn't recognise the header files location and I'm not really sure where to add those paths.
Can anyone give some hints to solve this?
If needed all the source files are in my Github repo CppLinuxVS.
UPDATE
As per comments on this post, below you can find the contents of the files:
CMakeLists.txt
project(CppLinuxVS)
cmake_minimum_required(VERSION 2.8.12)
add_definitions("-std=c++11")
# Download automatically, you can also just copy the conan.cmake file
if(NOT EXISTS "${CMAKE_BINARY_DIR}/conan.cmake")
message(STATUS "Downloading conan.cmake from https://github.com/conan-io/cmake-conan")
file(DOWNLOAD "https://raw.githubusercontent.com/conan-io/cmake-conan/v0.8/conan.cmake"
"${CMAKE_BINARY_DIR}/conan.cmake")
endif()
include(${CMAKE_BINARY_DIR}/conan.cmake)

UPDATE 2
Output of CMake inside VS2017 after downloading the conan.cmake file into the project instead of having the download specified in CMakeLists.txt. Also updated the CMakeLists.txt to require CMake 3.1.2 as per suggestion in the comments.

@lusocoding here is a project i setup to demonstrate a working combination of VS -> Cmake -> Conan.
https://github.com/solvingj/vs-cmake-conan-demo
One of the critical parts (as I recall) was CMakeSettings.json, which is supposed to be a machine-specific setting that you don't typically commit to git. However, at the time, there were customizations (i think it was the CLI flags passed to CMake) which i had to add to to make it work. So, i committed that file to git for the demonstration.
See if you can clone and use the project as is, and then slowly compare with your project to find differences.
Hope this helps.
