+ $ cmake -DOPENSSL_ROOT_DIR=/PATH/TO/OPENSSL/ ..
+
+If you use Visual Studio, you can also set `CMAKE_INSTALL_PREFIX` variable
+to set install path, like this:
+
+ > cmake -G "Visual Studio 15 Win64" -DCMAKE_PREFIX_PATH=c:\OpenSSL\vc-win64a\ -DCMAKE_INSTALL_PREFIX=c:\OpenSSL\vc-win64a\ ..
+
+Also instead of `cmake --build` tool you can just open `gost-engine.sln`
+in Visual Studio, select configuration and call `Build Solution` manually.
