# It built ${PSXRECOMP_GAME_SOURCES} — byte-for-byte the same source list as
# `psxrecomp-game` above — and was a leftover from before that target was
# introduced. Because Windows and macOS filesystems are case-insensitive, its
# output `PSXRecomp.exe` collided with the user-facing CLI `psxrecomp.exe`
# (the `psxrecomp` target above): both wrote the SAME file on disk and the
# last one linked won. In practice the CLI lost, so `psxrecomp.exe` shipped in
# `psxrecomp-cli-windows-x86_64.zip` (tools/build_cli.py) was actually the game
# recompiler, with a completely different argument grammar than the README
# documents. The bug is invisible on Linux, which is why it survived.
# The `PSXRecomp.exe` users are told to run in README's "Release Package"
# section is a DIFFERENT artifact — the BIOS-only runtime, whose name comes
# from OUTPUT_NAME in runtime/runtime.cmake — and is unaffected by this removal.
# See the collision guard at the bottom of this file.
