### Cross-compiling
To compile for a platform that isn't the same as the one you're building on,
set the `target_cpu` GN argument. For example, to compile a windows x86 target
from an x64 host, specify `target_cpu = "x86"` in `gn args`.
```sh
$ gn gen out/Default-x86 --args='... target_cpu = "x86"'
```
Not all combinations of source and target CPU/OS are supported by Chromium.
Only cross-compiling Windows 32-bit from Windows 64-bit has been tested in
Electron. If you test other combinations and find them to work, please update
this document :)
