Rand error while building the examples

[adelmagteleco]

When I put this command: cmake --build liboqs-cpp/build --target examples --parallel 8
I get this error:
[ 33%] Building CXX object CMakeFiles/sig.dir/examples/sig.cpp.o

It's my first time working with liboqs so I would erally appreciate any help, thank you so much!

Thanks for this bug report. This most likely is an unintended downstream side-effect of #1667. Tagging @SWilson4 fyi. Issue already created in the suitable sub project liboqs-cpp. I don't quite understand how/why this issue did not get caught by CI: Tagging @vsoftco for insights on that.

Resolved as per open-quantum-safe/liboqs-cpp#17
