did you try to build it using the bash script? like "sh build-cuda.sh" or "sh build.sh" (for non cuda)

It's still the same error, because the script content is only

cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --target clean --config Release
cmake --build . --target bladebit --config Release -j32

centos7 has no <sys/random.h>, you need to update your libc(and this is very difficult), update to newer kernel or use containers(docker or singularity) will be easier.
