This adds copyright/license notification blocks CMake's non-find
modules. Most of the modules had no notices at all. Some had notices
referring to the BSD license already. This commit normalizes existing
notices and adds missing notices.
This defines global, directory, and target properties
RULE_LAUNCH_COMPILE, RULE_LAUNCH_LINK, and RULE_LAUNCH_CUSTOM. Their
values specify 'launcher' command lines which are prefixed to compile,
link, and custom build rules by Makefile generators.
- Re-enable enforcement in cmMakefile::EnforceUniqueName
- Improve error message to help user resolve the problem
- Fix Modules/CTestTargets.cmake to not duplicate testing targets
- Move commands used by the changes to Modules/CTestTargets.cmake
to build during bootstrap: DEFINE_PROPERTY, GET_PROPERTY
