# opencv 4.10.0 — visión por computadora. Campaña KDE (ADR 0011): spectacle (la herramienta de CAPTURA DE
# PANTALLA) lo exige — `find_package(OpenCV 4.7 REQUIRED core imgproc)` (lo usa en src/QtCV.h para el
# detector de rectángulos/ventanas de la captura).
#
# OpenCV es enorme (~95MB de fuente, decenas de módulos). Se recorta a los DOS módulos que spectacle pide
# (core + imgproc) con BUILD_LIST, y se apaga todo lo demás: sin apps/tests/perf-tests/docs/examples, sin
# Python/Java, sin protobuf/DNN, sin GUI (highgui/gtk/qt), sin video/ffmpeg/gstreamer, sin IPP/TBB/CUDA.
# BUILD_LIST=core,imgproc hace que CMake ni configure los demás módulos.
#
# WITH_* de codecs OFF: OpenCV traería sus terceros (libjpeg/png/tiff/webp/openjpeg propios). imgproc no
# los necesita (los codecs viven en imgcodecs, que no construimos).
