# Set TARGET_FILTER to filter which targets to include (regex pattern)
# Examples:
#   set(TARGET_FILTER ".*")           # Include all targets (default)
#   set(TARGET_FILTER "ITSA_.*")      # Only ITSA targets
#   set(TARGET_FILTER "atcoder_.*")   # Only atcoder targets
#   set(TARGET_FILTER "aoc_2024_.*")  # Only aoc_2024 targets
#   set(TARGET_FILTER "hoj_.*")       # Only hoj targets
#   set(TARGET_FILTER "(ITSA|atcoder)_.*")  # Multiple categories
#
# Can also be set via command line: cmake -DTARGET_FILTER="ITSA_.*" ..
