shared by several projects. A robot replays changes committed there
into the Source/kwsys directory in CMake. Please send changes to
this directory separately. Run
git reset HEAD -- Source/kwsys
to unstage these changes and then
git diff -- Source/kwsys > kwsys.patch
to construct the patch. Alternatively, set environment variable
HOOKS_ALLOW_KWSYS=1
to disable this check and commit the changes locally.'
