Add to conan remotes bincrafters repository (a well known bunch of people who maintain many different packages that are not part of the conan-central yet.
conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
Then build the project like this:
cd /path/to/this/project
mkdir build
cd build
conan install --build=missing ..
cmake -DCONAN_USE_CMAKE_GENERATOR=OFF ..
OR as a last step (instead of cmake ...) to see a more intrusive conan usage
cmake -DCONAN_USE_CMAKE_GENERATOR=ON ..
