Description of Problem:

Trying to build openscap from the https://github.com/OpenSCAP/openscap/releases/download/1.3.10/openscap-1.3.10.tar.gz release but make fails with:

[ 79%] Building C object src/OVAL/CMakeFiles/oval_object.dir/oval_message.c.o
/tmp/openscap-20240627-8095-tmbe9s/openscap-1.3.10/src/common/util.c:332:9: error: incompatible integer to pointer conversion returning 'int' from a function with result type 'char *' [-Wint-conversion]
        return strerror_r(errnum, buf, buflen);
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

OpenSCAP Version:

1.3.10

Operating System & Version:

macOS Sonoma 14.5 (M1 arm64)

Steps to Reproduce:

1. Follow https://github.com/OpenSCAP/openscap/blob/main/docs/developer/developer.adoc#1-building-openscap-on-linux to get the release
2. When running any make command (make all, make openscap, or just make) it'll fail with the error above

Actual Results:

Error 2:

/tmp/openscap-20240627-8095-tmbe9s/openscap-1.3.10/src/common/util.c:332:9: error: incompatible integer to pointer conversion returning 'int' from a function with result type 'char *' [-Wint-conversion]
        return strerror_r(errnum, buf, buflen);
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Expected Results:

Binaries are compiled happily

Additional Information / Debugging Steps:

I'm actually trying to make a Homebrew formula to build and install the openscap binary. My hope is to be able to use oscap xccdf generate specifically less so the scanning features.
