Commit 8d0161c8 (Trust umask for file permissions, 2010-01-12) taught
these commands to set permissions to 0666 explicitly. The intention was
to let the open() call inside ofstream handle permsisions so that umask
would be honored. Now we set permissions only when we need to preserve
those on an existing file. New files will be created with umask-based
permissions.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
- CMake 1.8 and below did not do the check but could get in
infinite loops due to the local generate step.
- CMake 2.0 added the check but failed to perform it in directories
with no targets (see bug #678).
- CMake 2.2 removed the local generate which fixed the problem but
did not remove the check.
- Between CMake 2.4 and 2.6.0rc6 the check was fixed to work even
when no targets appear in a directory (see bug #6923).
- Bottom line: the check is no longer needed.
