abseil/absl missing from Docker image when trying to use FUZZ_TEST icw autotools

I'm trying to use FUZZ_TEST icw autotools, the Docker image contains fuzztest but abseil/absl appears to be missing

Could you clarify a bit, maybe a reproducer command? is the problem that compile_fuzztest.sh is not working or something different?

[joachimmetz]

When I include "fuzztest/fuzztest.h" and try to build the fuzz target compilation fails due to missing absl headers used in fuzztest.h [1]. But the absl headers do not appear to be included on the Docker image.

Manually running fuzztest Cmake configuration downloads a copy of absl in a temporary location. I could change the project Docker configuration to set up the absl source as a preparation step but given absl appears to be a dependency of fuzztest I found it strange that it is missing.

To reproduce current fuzz targets that do not use fuzztest https://github.com/libyal/libcaes/tree/main/ossfuzz

• change Makefile.am to include -I../../fuzztest
• change fuzz targets to use FUZZ_TEST
• build ossfuzz using https://github.com/libyal/libcaes/blob/main/.github/workflows/build_ossfuzz.yml
