 To compile optional modules (such as Schnorr signatures), you need to run `./configure` with additional flags (such as `--enable-module-schnorrsig`). Run `./configure --help` to see the full list of available flags. For experimental modules, you will also need `--enable-experimental` as well as a flag for each individual module, e.g. `--enable-module-musig`.
 
+Building with CMake (experimental)
+----------------------------------
+
+To maintain a pristine source tree, CMake encourages to perform an out-of-source build by using a separate dedicated build tree.
+
+### Building on POSIX systems
+
+    $ mkdir build && cd build
+    $ cmake ..
+    $ cmake --build .
+    $ ctest  # run the test suite
+    $ sudo cmake --build . --target install  # optional
+
+To compile optional modules (such as Schnorr signatures), you need to run `cmake` with additional flags (such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG=ON`). Run `cmake .. -LH` to see the full list of available flags.
+
+### Cross compiling
+
+To alleviate issues with cross compiling, preconfigured toolchain files are available in the `cmake` directory.
+For example, to cross compile for Windows:
+
+    $ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/x86_64-w64-mingw32.toolchain.cmake
+
+To cross compile for Android with [NDK](https://developer.android.com/ndk/guides/cmake) (using NDK's toolchain file, and assuming the `ANDROID_NDK_ROOT` environment variable has been set):
+
+    $ cmake .. -DCMAKE_TOOLCHAIN_FILE="${ANDROID_NDK_ROOT}/build/cmake/android.toolchain.cmake" -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=28
+
+### Building on Windows
+
+To build on Windows with Visual Studio, a proper [generator](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html#visual-studio-generators) must be specified for a new build tree.
+
+The following example assumes using of Visual Studio 2022 and CMake v3.21+.
+
+In "Developer Command Prompt for VS 2022":
+
+    >cmake -G "Visual Studio 17 2022" -A x64 -S . -B build
+    >cmake --build build --config RelWithDebInfo
