Function compileCPP

compileCPP(
sourcePath: string,
options?: { cppStandard?: string },
): Promise<void>
Compiles a C++ source file using g++. Uses -O2 optimization and the C++ standard from Config.json (cppStandard, default C++23). The problem root (current working directory) is added as a quoted-include search path so sources in subdirectories can #include "testlib.h". Goes through the compilation cache: when the source, its local headers, the flags, and the compiler are unchanged, the cached binary is restored and g++ is not run. A testlib program is compiled against a declarations-only testlib and linked with testlib compiled once per problem (see prebuilt-testlib.ts), falling back to the original header.
Parameters
- sourcePath: string
  Path to the .cpp / .cc / .cxx source file
- Optionaloptions: { cppStandard?: string } = {}
  Compilation overrides
  - OptionalcppStandard?: string
    Standard to pass as -std=; when omitted it is resolved from Config.json
Returns Promise<void>
Resolves once the executable is written next to the source (same path, extension stripped)
Throws
If file is not a C++ source or compilation fails
Example
```
await compileCPP('solutions/main.cpp');
// Produces: '/path/to/solutions/main'
```
