Brad King c332e0bf3c ENH: Isolate policy changes in included scripts
Isolation of policy changes inside scripts is important for protecting
the including context.  This teaches include() and find_package() to
imply a cmake_policy(PUSH) and cmake_policy(POP) around the scripts they
load, with a NO_POLICY_SCOPE option to disable the behavior.  This also
creates CMake Policy CMP0011 to provide compatibility.  See issue #8192.

Brad King 8997f4760a ENH: Refactor policy stack representation
This defines PolicyMap as a public member of cmPolicies.  Its previous
role as a policy stack entry is now called PolicyStackEntry and
represented as a class to which more information can be added later.

Brad King d524f3675e ENH: Improve argument parsing error messages
Previously error messages produced by parsing of command argument
variable references, such as bad $KEY{VAR} syntax or a bad escape
sequence, did not provide good context information.  Errors parsing
arguments inside macro invocations gave no context at all.  Furthermore,
some errors such as a missing close curly "${VAR" would be reported but
build files would still be generated.

These changes teach CMake to report errors with good context information
for all command argument parsing problems.  Policy CMP0010 is introduced
so that existing projects that built despite such errors will continue
to work.

David Cole bd1935dcd1 ENH: Improve FILE GLOB_RECURSE handling of symlinks with a new CMake policy. CMP0009 establishes NEW default behavior of not recursing through symlinks. OLD default behavior or explicit FOLLOW_SYMLINKS argument to FILE GLOB_RECURSE will still recurse through symlinks. 2008-09-11 14:34:04 -04:00
Brad King f50ed1fd88 ENH: Improve errors when a policy is REQUIRED
In the future some policies may be set to REQUIRED_IF_USED or
REQUIRED_ALWAYS.  This change clarifies the error messages users receive
when violating the requirements.

Brad King b93f0318fe ENH: Support full-path libs w/out valid names.
This change introduces policy CMP0008 to decide how to treat full path
libraries that do not appear to be valid library file names.  Such
libraries worked by accident in the VS IDE and Xcode generators with
CMake 2.4 and below.  We support them in CMake 2.6 by introducing this
policy.  See policy documentation added by this change for details.

Brad King 067717a56a BUG: Fix compatibility with CMake 2.4 for installation of MACOSX_BUNDLE targets
- Add policy CMP0006 to decide whether to use compatibility
  - OLD behavior is to fall back to RUNTIME rules
  - NEW behavior is to produce an error

Brad King bf4cef9d5c ENH: Add policy CMP_0004 to require library names to have no leading or trailing whitespace. Replace previous check of CMAKE_BACKWARDS_COMPATIBILITY against version 2.4 with the policy. 2008-03-13 16:35:39 -04:00
Brad King d46ff28ac9 ENH: Convert CMAKE_LINK_OLD_PATHS to policy CMP0003.
- 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

Brad King 5233b75a77 ENH: Improve handling of old-style compatibility.
- 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
