The README and web docs should have an installation guide, and should mention the examples folder.
Note that RandBLAS might be header-only, but if it's configured to use OpenMP then builds can still fail. For example, gcc and g++ on macOS are symlinked to system clang/clang++, which doesn't have OpenMP:
(base) s1104997ca:build rjmurr$ gcc -v
Apple clang version 15.0.0 (clang-1500.3.9.4)

From there, you need to run
export CC=clang
andexport CXX=clang++
before running CMake (or otherwise tell CMake to use these compilers).
