How to add MPICH library to CLion project? - c++

Question

I downloaded the mpich-3.3.2 archive (stable release) from the official site, unpacked it and concluded that I have the MPICH library. But I can’t add it to Clion. Here is my CMakeLists.txt:
cmake_minimum_required(VERSION 3.15)
project(MyProject)
set(CMAKE_CXX_STANDARD 17)
find_package(MPI REQUIRED)
include_directories(${MPI_INCLUDE_PATH})
SET(CMAKE_C_COMPILER mpicc)
SET(CMAKE_CXX_COMPILER mpicxx)
add_executable(MyProject main.cpp)
I tried to enter different things in CMakeLists.txt, but always the same thing:
-- Could NOT find MPI_C (missing: MPI_C_LIB_NAMES MPI_C_HEADER_DIR MPI_C_WORKS)
-- Could NOT find MPI_CXX (missing: MPI_CXX_LIB_NAMES MPI_CXX_HEADER_DIR MPI_CXX_WORKS)
CMake Error at C:/Program Files/JetBrains/CLion 2019.3.4/bin/cmake/win/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
Could NOT find MPI (missing: MPI_C_FOUND MPI_CXX_FOUND)
Call Stack (most recent call first):

What am I doing wrong? How should Clion find out the location of MPICH on my computer?
