 * Download and install [CMake](https://cmake.org/download/); choose "Add CMake to the system PATH" option while installing.
 * Build `TDLib` with CMake as explained in [building](#building), but instead of `cmake -DCMAKE_BUILD_TYPE=Release ..` use
 ```
-cmake -DCMAKE_TOOLCHAIN_FILE=<path to vcpkg>\scripts\buildsystems\vcpkg.cmake ..
+cmake -DCMAKE_TOOLCHAIN_FILE=<path to vcpkg>/scripts/buildsystems/vcpkg.cmake ..
 ```
 
 To build 32-bit/64-bit `TDLib` using MSVC, you will need to additionally specify parameter `-A Win32`/`-A x64` to CMake.
