Error while importing Boost 1.61.0 to C++ project - c++

Question

I tried to import Boost 1.61.0 (downloaded from SourceForge - Boost 1.61.0 as .7z), but failed.
Console:
"D:\Program Files (x86)\JetBrains\CLion 2016.2\bin\cmake\bin\cmake.exe" --build C:\Users\Marczak\.CLion2016.2\system\cmake\generated\WsServer-e351c9f9\e351c9f9\Debug --target WsServer -- -j 4

set(SOURCE_FILES src/main.cpp)
find_package(Boost)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(WsServer ${SOURCE_FILES})
If I do find_package(Boost 1.61.0 COMPONENTS system filesystem REQUIRED) I get:
Error: Unable to find the requested Boost libraries.
Boost version: 1.61.0
Boost include path: C:/Users/Marczak/boost_1_61_0
Could not find the following static Boost libraries:
boost_system boost_filesystem
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to the location of Boost.
I tried to set Boost_USE_STATIC_LIBRARIES on, but it failed too. I use CLion 2016.2.
UPDATE: I tried older versions too. Same error. What's inside the .7z:
In other topics I see lib folder. But here I don't see it. What I should put in BOOST_LIBRARYDIR?
UPDATE 2: Installed binary from https://sourceforge.net/projects/boost/files/boost-binaries/1.61.0/ . I noticed there's new folder: lib64-msvc-14.0. It contains many .dll and .lib files, e.g. boost_atomic-vc140-mt-1_61.dll.
Boost.org says:
If you plan to use your tools from the Windows command prompt, you're in the right place. If you plan to build from the Cygwin bash shell, you're actually running on a POSIX platform and should follow the instructions for getting started on Unix variants. Other command shells, such as MinGW's MSYS, are not supported—they may or may not work.
I'll try using Cygwin.

If you're new to C++, I suggest you to download MinGW distribution maintained by Stephan T. Lavavej (Microsoft C++ developer): https://nuwen.net/mingw.html. It, among other tools and libraries, contains pre-built boost binaries. Unpack it and specify the path to it via Settings | Build, Execution, Deployment | Toolchains.
After that you should be able to compile the program with the following CMakeLists.txt:
cmake_minimum_required(VERSION 3.5)
project(WsServer)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
set(SOURCE_FILES src/main.cpp)
find_package(Boost REQUIRED COMPONENTS filesystem)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(WsServer ${SOURCE_FILES})
target_link_libraries(WsServer ${Boost_LIBRARIES})
Don't forget to drop CMake cache as find_packages doesn't update successful results due to performance reasons (in CLion it can be done via Cmake toolbar | Cache | red arrows icon).
Some additional remarks:
Boost_USE_STATIC_LIBRARIES is not meant to be set manually, it is set by running find_package(Boost), which uses BOOST_ROOT or BOOST_INCLUDEDIR + BOOST_LIBRARYDIR, you should set those if required. You don't have to do it with the MinGW distro I've linked because it already has boost includes and libraries in accessible locations.
You can check that the paths to libraries are correct by looking at Boost_* variables in CMake cache.
libs directory inside boost sources is unrelated to the problem, it doesn't conitain any binaries
You've downloaded boost binaries built with Visual Studio toolchain, not MinGW, so they are incompatible with your setup. If you don't want to use MinGW package I've linked, you have to either find boost binaries built with correct MinGW version or build it yourself.
