RUNTIME, ARCHIVE, LIBRARY, etc.) arguments are given.
If the component of a part of a target is queried, return the specific one,
if a specific one hasn't been set, return the generic one, if that hasn't
been set, return "Unspecified".

- 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
- Give example code to avoid the warning
- Make explanation more consise
- Explicitly state this is for compatibility
- Issue the warning for at most one target
- This will help projects support multiple CMake versions.
- In order to set a policy when using a newer CMake but still
working with an older CMake one may write
if(POLICY CMP1234)
cmake_policy(SET CMP1234 NEW)
endif(POLICY CMP1234)
- Note that since CMake 2.4 does not have if(POLICY) supporting
it will also require using "if(COMMAND cmake_policy)"
- Update policy CMP0000 to require use of the command
cmake_minimum_required and not cmake_policy
so there is only one way to avoid it.
- Explicitly specify the line users should add.
- Reference policy CMP0000 only at the end.
- Fix policy CMP0000 documentation to not suggest
use of the cmake_policy command.
- Add a paragraph introducing the policy mechanism
- Explicitly introduce the CMP<NNNN>, OLD, and NEW notation
- Note that setting policies by CMake version is preferred
- Fix SET signature to use CMP<NNNN> notation
- Add more details about the policy stack
- Targets built in the tree now add compatibility paths too
- The warning message's first list includes at most one item
for each unique compatibility path
- Clarified error message further
- Policy is WARN by default so projects will build
as they did in 2.4 without user intervention
- Remove CMAKE_LINK_OLD_PATHS variable since it was
never in a release and the policy supercedes it
- Report target creation backtrace in warning message
since policy should be set by that point
- Add cmListFileBacktrace to record stack traces
- Move main IssueMessage method to the cmake class instance
(make the backtrace an explicit argument)
- Change cmMakefile::IssueMessage to construct a backtrace
and call the cmake instance version
- Record a backtrace at the point a target is created
(useful later for messages issued by generators)
- ZERO_CHECK should check all stamps in case
of parallel build (fixes complex test failure)
- ZERO_CHECK should not appear when
CMAKE_SUPPRESS_REGENERATION is on (fixes bug 6490)
- Remove CMP_0001 (no slash in target name) and restore
old CMAKE_BACKWARDS_COMPATIBILITY check for it
- Replace all checks of CMAKE_BACKWARDS_COMPATIBILITY
with cmLocalGenerator::NeedBackwardsCompatibility calls
- Create new CMP_0001 to determine whether or not
CMAKE_BACKWARDS_COMPATIBILITY is used.
(old = use, new = ignore)
- Show CMAKE_BACKWARDS_COMPATIBILITY in cache only when
CMP_0001 is set to OLD or WARN
- Update documentation of cmake_policy and cmake_minimum_required
to indicate their relationship and the 2.4 version boundary
- When no cmake policy version is set in top level makefile
implicitly call cmake_policy(VERSION 2.4) which restores
CMAKE_BACKWARDS_COMPATIBILITY and other 2.4 compatibility
- Fix tests MakeClean and Preprocess to call
cmake_policy(VERSION 2.6) because they depend on new policies
- Add cmMakefile methods IssueError and IssueWarning
- Maintain an explicit call stack in cmMakefile
- Include context/call-stack info in messages
- Nested errors now unwind the call stack
- Use new mechanism for policy warnings and errors
- Improve policy error message
- Include cmExecutionStatus pointer in call stack
so that errors deeper in the C++ stack under
a command invocation will become errors for the
command
