+- vcpkg

+## Notes
+
+1. Build number
+
+   You can change the build number in `CMakeSettings.json`. Use any integer no less than 5180.
+
+   Delete and regenerate CMake cache after the change.
+
+1. 32-bit Windows
+
+   You don't need 32-bit Windows to build 32-bit executables. However, if 32-bit Windows is what you only have, things become a little complicated.
+
+   Visual Studio 2019 is the last version that works on 32-bit Windows. It does the job but its bundled CMake and Ninja are 64-bit versions.
+
+   After the installation of VS 2019, you need to download 32-bit CMake and Ninja and replace those that come with VS in:
+
+   ```
+   C:\Program Files\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake
+   ```
+
+   Currently CMake has an official x86 installer but Ninja does not. You may need to download from a 3rd party or build from source.
