When running clang-include-cleaner, the tool performs static analysis by
"compiling" specified source files. Previously, non-existent included headers
caused the tool to skip source files, reducing the effectiveness of unused
include detection.
Problem:
- Header files like 'rust/wasmtime_bindings.hh' were not pre-generated
- Compilation errors led to skipping source file analysis
```
/__w/scylladb/scylladb/lang/wasm.hh:15:10: fatal error: 'rust/wasmtime_bindings.hh' file not found
15 | #include "rust/wasmtime_bindings.hh"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Skipping file /__w/scylladb/scylladb/lang/wasm.hh due to compiler errors. clang-include-cleaner expects to work on compilable source code.
1 error generated.
```
- This significantly reduced clang-include-cleaner's coverage
Solution:
- Build the `wasmtime_bindings` target to generate required header files
- Ensure all necessary headers are created before running static analysis
- Enable full source file checking for unused includes
By generating headers before analysis, we prevent skipping of source files
and improve the comprehensiveness of our include cleaner workflow.
