##### Build-System Integration #################################################

# Grounds the CMake behavior doc/TopicCMakeGuide.dox documents: find_package
# against an installed tree, the version-range contract of the hand-written
# Eigen3ConfigVersion.cmake, embedding via add_subdirectory, and the ways an
# embedding project opts out of Eigen's install rules.
#
# Self-contained, so it neither extends .test:linux nor needs a build job: the
# scenarios run their own nested configures against the checkout, and the
# enclosing build directory holds only the CTest definitions.  Staying off
# .test:linux also keeps it off the pass cache, which keys on a test's
# executable -- these tests have none, so a recorded pass would outlive any
# change to Eigen's CMake files.
#
# Cheap -- a nested configure and a small compile per scenario, six seconds of
# script on the runner, inside a job that takes half a minute once the image
# pull and checkout are counted -- but still gated on the files that can make
# it fail rather than run on every merge request: Eigen's own CMake surface,
# the guide it grounds, and the job's own definition and script. A push to the
# default branch runs it unconditionally, as the backstop for whatever the path
# list does not anticipate.
#
# Not behind the all-tests label, unlike the documentation job it complements:
# that label is why an incorrect claim in the CMake guide reached a release
# unnoticed, and an MR that edits these files is exactly the MR that needs the
# answer before merge rather than after.
