Ninja generator ensures that all custom commands being target
dependencies are run before other source compilations. However in case
there are no such dependencies it currently generates empty phony rules
which clutter the build graph.
Teach the Ninja generator to produce such rules only when necessary.
Actually custom command can write wherever it wants to, such as temporary
folder or source folder, possibly violating rules that only build folder should
be affected. Therefore we should consider custom command dependency at any path
as possible side effect adding phony rule.
We avoid adding phony rules for regular source files (since the paraent
commit) so we no longer need the in-build-tree test to avoid them.
Since commit v2.8.12~248^2 (Ninja: Custom Command file depends don't
need to exist before building, 2013-06-07) all explicit dependencies
inside build folder were considered as possible build command
side-effects and phony rules were produced for them in case they don't
exist when starting to build. This is unnecessary since regular compile
inputs need to exist or cmake will fail. Moreover the exception for
sources having GENERATED property that can be missing is already handled
by WriteAssumedSourceDependencies.
This fixes unwanted phony rules for all regular source files when doing
in-source build, causing Ninja not complain when such files gets missing,
i.e. during development. Also this reduces number of rules in ninja.build.
Now only custom command dependencies are considered as possible side-effects.

The check for this flag added by commit v3.0.0-rc1~284^2 (UseSWIG: Name
python module according to swig flags, 2013-11-26) can get false
positives on flags like "-noproxydel". Improve the check to match only
"-noproxy".

Since commit v3.0.0-rc1~374^2 (Refactor internal resource location APIs
and initialization, 2013-11-07) a bootstrap-built "cmake" tries to
reference "ctest" and "cpack" executables next to itself, which never
exist. Teach cmSystemTools::FindCMakeResources, when bootstrap-built,
to refer to the "ctest" and "cpack" executables in the location where
they will be built after "make".

The ctest launcher code did not respect the number of errors and
warnings limits. Limit the number of launcher report fragments that we
report in the final submission.
Use LinkImplementationPropertyEntries directly instead of asking
GetProperty to construct a string for LINK_LIBRARIES. This gives us
access to the entry backtraces.
If ComputeLinkImplementationLanguages were ever to cause
GetLinkImplementationLibraries to be invoked then a LinkImplMap entry
may appear in the middle of computing it in GetLinkInformation. Instead
create the map entry up front and store in it boolean values indicating
which pieces of the LinkImplementation structure have been populated.
This approach leads to shorter code that is easier to follow too.
Members of the cmTargetInternals structure do not need to be made
'mutable' even to cache data because there is no reason for the
internal methods to be 'const'.
Teach GetTransitivePropertyTargets to use the GetLinkInterfaceLibraries
method with usage_requirements_only==true instead of evaluating the
INTERFACE_LINK_LIBRARIES property directly. This avoids duplicate
evaluations and makes use of the caching done by
GetLinkInterfaceLibraries.
Add a 'usage_requirements_only' parameter to GetLinkInterfaceLibraries
and supporting internal APIs to pass through to ExpandLinkItems so it
knows whether to use SetTransitivePropertiesOnly while evaluating
generator expressions.
Simplify the implementation of GetTransitivePropertyTargets by using
ExpandLinkItems with usage_requirements_only==true to evaluate the
generator expressions in the link interface for us.
Add a 'usage_requirements_only' parameter to ExpandLinkItems so that it
knows whether to use SetTransitivePropertiesOnly while evaluating
generator expressions. Update existing call sites to pass 'false' since
they are for linking and not usage requirements.
Since commit 6557382d (stringapi: Use strings for program
paths, 2014-02-24), cmGlobalGenerator::GenerateBuildCommand
takes the make program path as a std::string. Fix the lookup
in cmCPackGenerator::InstallProjectViaInstallCMakeProjects to
use GetSafeDefinition for CMAKE_MAKE_PROGRAM to avoid possible
construction of std::string from a NULL.

Installing large directories, e.g., the output of a doxygen run, prints
one line per file resulting in too much noise in the build output. Add
an option to the install(DIRECTORY) command to not print anything upon
make install.
Extend the RunCMake.install test with cases covering MESSAGE_NEVER
behavior of the install(DIRECTORY) command.
Suggested-by: Stefan Eilemann <Stefan.Eilemann@epfl.ch>
Create a variable to allow users to control which installation
messages are printed. In particular, provide a "LAZY" setting
that prints "Installing" messages but not "Up-to-date" messages.
This is desirable for incremental re-installations.

Create a cmInstallGenerator::MessageLevel enumeration for future use in
specifying install message verbosity. Thread values of the type through
constructors and save the value as a member of cmInstallGenerator.
Use only a "MessageDefault" value for now.
Create options "MESSAGE_ALWAYS", "MESSAGE_LAZY", and "MESSAGE_NEVER" to
specify whether to print the "Installing" and "Up-to-date" messages.
Extend the RunCMake.file test with cases covering these options.
Teach cmFileCopier::InstallDirectory to detect whether the destination
directory exists. If so, report it as "Up-to-date" instead of
"Installing". This resolves message asymmetry with file installations.
Extend the RunCMake.file and RunCMake.install tests to check the
installation output on both the first and second run.
Suggested-by: J Decker <d3ck0r@gmail.com>
When installing a DIRECTORY, do not pre-create the DESTINATION. The
cmFileCopier::InstallDirectory method will create the directory anyway.
Give it a chance to detect whether the directory already exists or not.
