# ---------------------------------------------------------------------------
# One executable for the corelib unit tests, source files kept split.
#
# Every test binary that links rtabmap_core pulls in ~344 shared libraries
# (PCL, VTK, OpenCV, Qt, g2o, GTSAM, Ceres, octomap, the camera SDKs...), and
# each ctest entry is a separate process that pays that load cost again. The
# load dominates: test_util3d_transforms does ~10 ms of actual work, yet it
# reported 12.7 s on the macOS runners, where dyld has no shared cache for
# non-system dylibs and validates each one's signature per process. Roughly
# 590 s of a 2150 s macOS run was process startup.
#
# gtest registers tests through static initializers and gtest_main supplies
# main(), so the sources combine into one target with no source changes.
