# libFuzzer harness(es) for IfcOpenShell. Only built when BUILD_FUZZERS is ON,
# which is expected to be paired with a Clang toolchain configured with
# -fsanitize=fuzzer (and typically also address,undefined) in
# CMAKE_CXX_FLAGS - this target does not add sanitizer flags itself.

# -fsanitize=fuzzer supplies its own main() and libFuzzer's driver, so it
# must stay scoped to this one executable rather than going in the global
# CMAKE_CXX_FLAGS - every other target (including CMake's own compiler
# checks) would otherwise fail to link. ASan/UBSan, by contrast, are applied
# globally via CMAKE_CXX_FLAGS so that IfcParse itself is instrumented.
