Behdad Esfahbod e0aee5815a [test] Respect MESON_EXE_WRAPPER in more test runners 
It's not working for me though. Meson doesn't seem to set WINEPATH
during testing.

README.md

To build the fuzzers with libFuzzer to perform actual fuzzing, build with:

CXX=clang++ CXXFLAGS="-fsanitize=address,fuzzer-no-link" meson fuzzbuild --default-library=static -Dfuzzer_ldflags="-fsanitize=address,fuzzer"

ninja -Cfuzzbuild

Then, run the fuzzer like this:

fuzzbuild/test/fuzzing/hb-{shape,draw,subset,set}-fuzzer [-max_len=2048] [CORPUS_DIR]

Where max_len specifies the maximal length of font files to handle. The smaller the faster.
