You *must* use special compiler flags to build your library and fuzzers.
These flags are provided in following environment variables:
| Env Variable | Description
| ------------- | --------
| `$CC` | The C compiler binary.
| `$CXX`, `$CCC` | The C++ compiler binary.
| `$CFLAGS` | C compiler flags.
| `$CXXFLAGS` | C++ compiler flags.
| `$LDFLAGS` | Linker flags for fuzzer binaries.
| Env Variable | Description
| ------------- | --------
| `$CC`, `$CXX`, `$CCC` | The C and C++ compiler binaries.
| `$CFLAGS`, `$CXXFLAGS` | C and C++ compiler flags.
| `$FUZZER_LDFLAGS` | Linker flags for fuzzer binaries.
Many well-crafted build scripts will automatically use these variables. If not,
passing them manually to a build tool might be required.
