CMake error: Imported targets not available for Boost version 106300

I am trying to use uint512_t in a boost library located in:

multiprecision/cpp_int.hpp

however, when I try to include my boost library through CMake:

cmake_minimum_required(VERSION 3.6)
project(BoostTest)

set(CMAKE_CXX_STANDARD 11)
set(BOOSTROOT "/usr/local/Cellar/boost/1.63.0/include")

find_package(Boost REQUIRED)
if (Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIR})
endif()

include_directories(${Boost_INCLUDE_DIR})

set(SOURCE_FILES main.cpp)
add_executable(BoostTest ${SOURCE_FILES})

I receive the following error message when compiling:

error: unknown type name 'uint512_t'

I don't know what the problem is. I even included:

"boost/multiprecision/cpp_int.hpp"

Keeping everything else the same in main.cpp, all that was needed was:

using namespace boost::multiprecision
