CMake options:
- Build release optimized (better runtime performance): `-DCMAKE_BUILD_TYPE=Release`
- Use clang+lld (faster linking): `-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++`
- Optimize for current CPU (resulting binaries are not portable): `-DURDE_VECTOR_ISA=native`
