# engine_smoke — gamedev stack smoke test. Issue 0072a.

# Two build modes:

# 1. As subdir of cpp/ (cmake -S cpp -B build): cpp/CMakeLists.txt already
|

# adds vendor/sdl3 and exposes SDL3::SDL3-static. We just link.
|
|
# 2. As top-level (cmake -S cpp/apps/engine_smoke -B build) — used by the
|
|
# WASM pipeline and any standalone build. We do project() + manually
|
|
# add_subdirectory the vendored SDL3.
