[build]
# The four libraries, vendored from the v1.6.0 release under
# upstream/recastnavigation (upstream/documents.json: the release tarball,
# each file's checksum, and which files patches/ changed) and built as
# upstream's CMake build does, without DebugUtils and the demo. Every platform
# makes the same mesh, path and crowd step from the same input: the compiler
# fuses no multiply and add into one rounding (arm64's default does, x86-64's
# cannot without FMA) and keeps IEEE semantics (no fast math), and no
# trigonometry comes from the platform's C library, whose cosf and sinf differ
# by an ulp between glibc, macOS, the Windows UCRT and emscripten: Detour's
# crowd and tile cache call Detour's own hooks (patches/0001; they called
# cosf and sinf directly), and the hooks (dtMathCosf, dtMathSinf,
# dtMathAtan2f) and Recast's walkable-slope cosf call port/DeterministicMath.cpp
# (patches/0002: IEEE arithmetic only, within 1 ulp of the correctly rounded
# float). sqrtf, floorf, ceilf and fabsf are exact under IEEE everywhere.
# patches/0003: with an even adaptiveDivs the crowd sampled an uninitialised
# direction (upstream issue #496), which no flag makes the same everywhere.
# patches/0004: the BV tree and the contours' hole merging sort with
# std::stable_sort instead of the C library's qsort, which is not stable and
# orders equal keys differently between glibc, macOS, the Windows UCRT and
# emscripten's musl, so a mesh with ties had different bytes by platform.
# NDEBUG: the same library in every profile — upstream declares its assert
# hooks (rcAssertFailSetCustom, dtAssertFailSetCustom) and checks only when
# NDEBUG is not defined, which would make the module's names differ between a
# dev and a release build.
