This reverts commit 242c3966 (add_custom_command: Diagnose
MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
The previous example for CMP0054 did not show how critical the policy is
since the result is the same in both cases (NEW and OLD behavior).
Instead show an example when the policy does make a difference.
Add sections to the cmake-buildsystem(7) manual and cross-reference
them with relevant variables and target properties. This avoids
duplicating the information and allows it to be more detailed.
46f6a5f4 cmState: Store the Current directories.
3a041c59 Introduce cmState::Snapshot.
ae6c8a9d cmState: Store the Source and Binary directories.
86f3cd0f cmMakefile: Require the localGenerator in the constructor.
a48aebcb cmLocalGenerator: Require a parent in the constructor.
e4c78b37 cmMakefile: Inline SetHome* methods into last remaining caller.
410f39a4 cmMakefile: Delegate storage of Home dirs to the cmake class.
Many projects put their project() call first, but the actions taken
by this command can be influenced by policies and other information
set by a call to cmake_minimum_required. Document in each of these
two commands that cmake_minimum_required should be called first.

The documentation of this variable in the CTest module is outdated
and has been superseded by the ctest(1) manual. In particular, the
latter mentions that it works with the Ninja generator as well as
makefile generators. Remove the documentation from the CTest module
and replace it with a link to the main variable documentation (which
already references the ctest(1) manual).
Create snapshots for buildsystem directories during configure time.
This class will be extended in follow up commits to snapshot
all values in the cmState.
Check that a non-optional file exists before attempting to include
it. This makes more sense than relying on an error case deeper
within cmListFileCache.
Use more reliable logic to detect if a path ends in ".framework". The
old logic added by commit v2.4.0~791 (add better support for framework
linking, 2005-12-26) did not account for paths not ending in it at all.
With a 9-character path the logic and "npos == -1" happens to make the
old check pass.
Fix the logic added by commit v3.0.0-rc5~9^2
(InstallRequiredSystemLibraries: MBCS MFC is optional on VS 12,
2014-05-06). Do not test content of MSVC${v}_MFC_DIR until after the
variable is set.
