3. Run CMake. The basic syntax is:
```
cmake [-G generator] [-DYAML_BUILD_SHARED_LIBS=ON|OFF] ..
cmake [-G generator] [-DBUILD_SHARED_LIBS=ON|OFF] ..
```
* The `generator` is whatever type of build system you'd like to use. To see a full list of generators on your platform, just run `cmake` (with no arguments). For example:
* On Windows, you might use "Visual Studio 12 2013" to generate a Visual Studio 2013 solution or "Visual Studio 14 2015 Win64" to generate a 64-bit Visual Studio 2015 solution.
* On OS X, you might use "Xcode" to generate an Xcode project
* On a UNIX-y system, simply omit the option to generate a makefile
* yaml-cpp defaults to building a static library, but you may build a shared library by specifying `-DYAML_BUILD_SHARED_LIBS=ON`.
* For more options on customizing the build, see the [CMakeLists.txt](https://github.com/jbeder/yaml-cpp/blob/master/CMakeLists.txt) file.
4. Build it!
5. To clean up, just remove the `build` directory.
### Cross Compile Dynamic Library for Android
* The 3rd step above can do like this:
```
cmake -DCMAKE_TOOLCHAIN_FILE=${NDKROOT}/build/cmake/android.toolchain.cmake -DANDROID_STL=c++_shared -DANDROID_PLATFORM=android-26 -DANDROID_ABI=x86_64 -DBUILD_ANDROID_LIBS=ON ..
```
- To do cross-compiling, `ndk-bundle`OR `android-sdk` is needed. Also `NDKROOT` should be exported in your `bash` config file, just like:
```
export NDKROOT=~/Library/Android/sdk/ndk-bundle
```
- The arguments `ANDROID_ABI` can be set to `arm64-v8a`, `armeabi-v7a`, `armeabi`, `x86`, `x86_64`， etc. If NOT set, the default value is `armeabi-v7a`.
- The arguments `ANDROID_PLATFORM` can be set to `android-xx` OR `latest`, `xx` can be replaced to the android api number, the default value will be the minimum supported version of your `ndk-bundle`, while the value `latest` will using the maximum supported version.
- `BUILD_ANDROID_LIBS=ON` will default set `BUILD_SHARED_LIBS=ON`, and copy the `libc++_shared.so` to `build` directory from `ndk-bundle`, which maybe needed by `libyaml-cpp.so`.
