* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | 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.
* ENH: Create policy scope barriersBrad King2009-01-221-10/+4
| | | | | This creates a barrier mechanism to prevent user code from using cmake_policy(POP) to pop a scope it didn't push with cmake_policy(PUSH).
* ENH: Add cmake_policy(GET) command modeBrad King2008-08-181-0/+61
| | | | | | | It is likely that projects or CMake modules in the future will need to check the value of a policy setting. For example, if we add a policy that affects the results of FindXYZ.cmake modules, the module code will need to be able to check the policy.
* ENH: Cleanup policy version interface presented to user.Brad King2008-03-241-8/+1
| | | | | | | - In cmake_minimum_required do not set policy version if current CMake is too old - In cmPolicies::ApplyPolicyVersion report error if version is too new or cannot be parsed
