autobuild priority

detect conan  →  found → conan2 build
     ↓ not found

system mode support

OS	system mode	Installation
Linux	✅	`apt install libhyperscan-dev`
macOS	✅	`brew install hyperscan`
Windows	❌ (skipped)	Use vcpkg instead

Supported targets

Architecture	Hyperscan	Vectorscan	vendored backend
x86_64	✅	✅	hyperscan-src
aarch64/arm64	❌	✅	vectorscan-src
ppc64/riscv/others	❌	❌	vectorscan-src (SIMDe)

Backend selection

build.rs auto-selects based on the TARGET environment variable:

x86_64: Hyperscan (all modes)
- Prebuilt packages for Linux x86_64 include AVX-512 instructions, which may SIGILL on unsupported CPUs → force FAT_RUNTIME source build
Non-x86_64: Vectorscan (Hyperscan only supports x86_64)
