Pass generated shard paths via a SOURCES_FILE so cmake -P is not killed by CreateProcess's ~8191-char limit, and keep has_bios on for OpenBIOS-only setup SDKs so the first-run wizard still offers SCPH1001. Co-authored-by: Cursor <cursoragent@cursor.com>

# check_generated_sources.cmake — fail the build with a HUMAN message when a
|
|
# game's recompiled C is missing, instead of letting the C compiler emit a raw
|
|
# "cc1: fatal error: <file>: No such file or directory".
|
|
#
|
|
# The runtime links generated/<serial>_{full,dispatch}.c, which are produced by
|
|
# a SEPARATE step (the recompiler tool) that a from-source builder runs before
|
|
# cmake --build. Those paths are marked GENERATED in CMake so `cmake configure`
|
|
# succeeds before the first generation — which means a skipped generation step
|
|
# is only discovered deep in the build as an inscrutable compiler error naming a
|
|
# file the user has no reason to know how to produce. This script is run as a
|
|
# build-time dependency of the runtime target (see psxrecomp_add_runtime_target)
|
|
# so the failure surfaces first, names the missing files, and states the fix.
|
|
#
|
|
# Invoked via:
|
|
# cmake -DSOURCES_FILE=<path> -DTARGET=.. -DGAME_CONFIG=.. \

# -DRECOMPILER=.. -DDOC=.. -P check_generated_sources.cmake
|
