watchman --version always return 0.0.0 when building from source

[derfsubterfuge]

I'm on Fedora 39. I followed the build from source instructions and augmented them with the final steps of prebuilt binaries. Whenever I run watchman --version I get 0.0.0 instead of the actual version. How do I correct this? Do I need to add a version.txt file somewhere?

Commands that I ran:

  # From build from source
  WATCHMAN_VERSION="v2024.03.25.00"
  WATCHMAN_BUILD_DIR="$(mktemp -d)"
  cd $WATCHMAN_BUILD_DIR
  wget "https://github.com/facebook/watchman/archive/refs/tags/$WATCHMAN_VERSION.tar.gz"
  tar -xvzf "$WATCHMAN_VERSION.tar.gz"
  cd "watchman-$(echo $WATCHMAN_VERSION | sed 's/v//g')"
  sudo dnf install -y cargo
  sudo ./install-system-packages.sh
  ./autogen.sh

  # From prebuilt binaries
  cd built
  sudo mkdir -p /usr/local/{bin,lib} /usr/local/var/run/watchman
  sudo cp bin/* /usr/local/bin
  sudo cp lib/* /usr/local/lib
  sudo chmod 755 /usr/local/bin/watchman
  sudo chmod 2777 /usr/local/var/run/watchman

  # Cleanup
  cd "$HOME"
  rm -rf $WATCHMAN_BUILD_DIR

  # Version command that returns 0.0.0
  watchman --version

You can override by setting WATCHMAN_VERSION_OVERRIDE to the desired version. See

watchman/CMakeLists.txt

Lines 92 to 103 in 4744a9d

	# A nonsensical version that doesn't correspond to any manually
	# released version.
	set(PACKAGE_VERSION "0.0.0")
	set(WATCHMAN_VERSION_OVERRIDE "" CACHE STRING "Use this version code for \
	Watchman version instead of the default computed from the repo")
	set(WATCHMAN_BUILDINFO_OVERRIDE "" CACHE STRING "Use this version code for \
	Watchman build info instead of the default (nothing)")
	if (WATCHMAN_VERSION_OVERRIDE)
	set(PACKAGE_VERSION "${WATCHMAN_VERSION_OVERRIDE}")
	elseif(DEFINED ENV{WATCHMAN_VERSION_OVERRIDE})
	set(PACKAGE_VERSION "$ENV{WATCHMAN_VERSION_OVERRIDE}")

Package info shows that version is 2021.05.10.00, but watchman itself shows 0.0.0.
