- Exclude platform-specific includes (anything in < >) from the clang preprocessor by using `!defined(GENERATING_CEF_API_HASH)` in CEF header files. - Define "target platforms" by passing platform- and architecture- specific ifdefs to the clang preprocessor. Grep for `defined(OS_` to identify headers that require target platform processing, and then process for each target as the platform-specific API hash contribution. - Delete the univeral hash which is no longer a useful concept.
