title: Cannot build a cmake project in Visual Studio and vcpkg (fatal error C1083)
body: <p>I installed vcpkg today, enabled integration with Visual Studio, ie .\vcpkg integrate install, and started installing libraries.</p>
  
  <p>I basically installed cpprestsdk and that trigger installation of boost libraries. Then I opened the project in the Visual Studio (CMake).</p>
  
  <p>When I installed cpprestsdk I received this message:</p>
  
  <pre><code>The package cpprestsdk:x86-windows provides CMake targets:
  
      find_package(cpprestsdk REQUIRED)
      # Note: 1 targets were omitted
      target_link_libraries(main PRIVATE cpprestsdk::cpprest cpprestsdk::cpprestsdk_boost_internal cpprestsdk::cpprestsdk_zlib_internal cpprestsdk::cp
  prestsdk_openssl_internal)
  
  The package cpprestsdk:x64-windows provides CMake targets:
  
      find_package(cpprestsdk REQUIRED)
      # Note: 1 targets were omitted
      target_link_libraries(main PRIVATE cpprestsdk::cpprest cpprestsdk::cpprestsdk_boost_internal cpprestsdk::cpprestsdk_zlib_internal cpprestsdk::cp

  <p>So my CMakeLists.txt </p>

  <p>However when I build the project I am taking some errors regarding boost</p>
  
  <blockquote>
    <p>c:\code\cpprest-client\multipartformdata.cpp(16): fatal error C1083:
    Cannot open include file: 'boost/uuid/random_generator.hpp': No such
    file or directory</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>c:\code\cpprest-client\api\userapi.h(36): fatal error C1083: Cannot
    open include file: 'boost/optional.hpp': No such file or directory</p>

  <p>In my powershell I see those libraries installed</p>
  
  <pre><code>PS C:\vcpkg\packages&gt; ls .\boost-uuid_x86-windows

  <p>Any ideas, what is going on. I have already lost hours with this.</p>
