title: Using Cmake-gui and vcpkg
body: <p>I am testing vcpkg for my project and I came across a problem with cmake-gui</p>
  
  <p>I have installed vcpkg, with the help of vcpkg Boost libraries were installed. When I compile via command line, everything works as it should.
  I use command </p>
  
  <pre><code>cmake .. -DCMAKE_TOOLCHAIN_FILE=D:/repos/vcpkg/scripts/buildsystems/vcpkg.cmake -G"Visual Studio 15 Win64"
  </code></pre>
  
  <p>But the problem is when I want to use cmake-gui to generate build files. It reports that Boost is not found.</p>
  
  <p>I tried to add </p>
  
  <pre><code>set(CMAKE_TOOLCHAIN_FILE "D:/repos/vcpkg/scripts/buildsystems/vcpkg.cmake" CACHE STRING "Path for vcpkg.cmake")
  </code></pre>
  
  <p>to the top of my Makefile, but it did not help. I also tried with add_definitions and add_compile_options, without success.</p>
  
  <p>So what should I add to my cmake file to be able to use cmake-gui with vcpkg ? </p>
