# Dual-mode CMakeLists.txt for simde (header-only library)
#
# NOTE: simde upstream uses meson, but we bypass it entirely because:
# 1. simde is header-only - no compilation needed
# 2. meson adds complexity and cross-platform issues (Windows link.exe errors, etc.)
# 3. All we need is to copy headers and generate a simple pkg-config file
# 4. Manual installation is simpler, faster, and identical across all platforms
#
# This approach is uniform on Linux and Windows - no surprises.
# IMPORTANT: Keep version in sync with URL below
