Rakefile

require 'nokogiri'

namespace 'conan' do
    desc 'Export Conan binary directories to the CONAN_BINARY_DIRECTORIES environment variable'
    task :export_env do
        doc = File.open('conanbuildinfo.props') { |f| Nokogiri::XML(f) }
        paths = doc.search("ConanBinaryDirectories").first.text
        `setx.exe CONAN_BINARY_DIRECTORIES "#{paths}"`
    end
end

This Rakefile can be used to parse through the Visual Studio property sheet generated by Conan (conanbuildinfo.props) and extract out the directory paths containing any binaries (i.e., .dlls) and set the CONAN_BINARY_DIRECTORIES environmental variable. This allows a Visual Studio project to link with runtime dependencies which is useful for running tests.

To use it, simply place this file in your project folder, install Nokogiri (gem install nokogiri), and run rake conan:export_env. Cheers!
