Avoid a separate open/close for each file installed.  Use a single

Stephen Kelly 72537e4436 Features: Add dialect compile flags only if default is known.
The CMAKE_<LANG>_STANDARD_DEFAULT variable indicates whether the
compiler has any notion of standard levels and that CMake knows
about them.  If no language standard levels are available, skip
all logic to attempt to add a flag for the level.

Also fail with an internal error if a bad default value is set.

Ben Boeckel dea42d9296 install: Fix regression in default configuration selection
The refactoring in commit v3.1.0-rc1~812^2~16 (stringapi: Pass
configuration names as strings, 2014-02-09) broke the code path in
cmLocalGenerator::GenerateInstallRules that intends to pick a default
install configuration for multi-config generators.  Fix the logic to
select an empty default configuration only when using a single-config
generator whose CMAKE_BUILD_TYPE is not set.

Brad King 3228fc5049 Features: Define meaning for no language standard default
Define an empty string in CMAKE_<LANG>_STANDARD_DEFAULT to mean that
the toolchain has no notion of lanuage standard levels.  In this case
the <LANG>_STANDARD[_REQUIRED] properties will have no effect.

Update the RunCMake.CompileFeatures test to exclude the
LinkImplementationFeatureCycle test when there is no standard default.
It can never fail because no use of specific features will adjust the
CXX_STANDARD level required for any target since the standard levels
have no meaning in this case.

Stephen Kelly b80557c7bd file(GENERATE): Evaluate early to allow generating source files
The evaluation files must be known before cmTargetTraceDependencies
attempts to find them, but we must actually generate the files after
cmTargetTraceDependencies, as that can add to target SOURCES.  The
limitation is that the generated output name must not depend on the
SOURCES of a target if the generated file is used by that target.

Mark the output files as GENERATED so that trace dependencies does
not expect them to already exist in the filesystem.

Move the invokation of ForceLinkerLanguage in the Generate logic
to after the generated file names are known.  ForceLinkerLanguage
tries to determine the sources of a target (in order to determine
an already-known language) and otherwise fails to get information
about the generated file.

Test that the output of file(GENERATE) can be used as a target source
file and that accessing the target SOURCES in the name of the output
file is an error.  Accessing the TARGET_OBJECTS would be a similar
error if it was legal to use that generator expression in this
context.  That is not currently possible and is a different error
condition, so test the current error output as a reminder to change
the expected output if that becomes possible in the future.  Test
that generated rule files resulting from cmTargetTraceDependencies
appear in the SOURCES generated in the output file.

Brad King f4c5eade78 Ninja: Fix RC include directories regression
Changes in commit b9aa5041 (cmLocalGenerator: Simplify GetIncludeFlags
output formatting, 2014-03-04) caused Windows Resource Compiler include
directories to be computed as relative paths in the Ninja generator.
This breaks the cmcldeps handling of include paths.  The reason for the
regression is that several cmLocalGenerator::GetIncludeFlags callers
treated the fourth "bool forResponseFile" argument as if it controlled
whether include directories were a full path.  It actually did control
that by accident until the above commit.

Add an explicit "bool forceFullPaths" argument to GetIncludeFlags
and thread the value through ConvertToIncludeReference as needed.
Update GetIncludeFlags call sites that really wanted to control the
forResponseFile setting to be aware of the new argument.  Extend the
VSResource test to cover this case.

Brad King c491cb1eb4 Fix some generator crashes on undefined CMAKE_BUILD_TYPE
Since commit 84fdc9921 (stringapi: Pass configuration names as strings,
2014-02-09), it is not safe to use GetDefinition("CMAKE_BUILD_TYPE")
without checking the return value.  Use GetSafeDefinition instead so
that a missing definition is treated as an empty string like code paths
did prior to the above commit.

Brad King 8256ccb78c Add OBJECT_FILE_DIR rule placeholder for compilation lines
Some compilers do not offer an option to specify the path to the object
file, but rather only to the directory in which to place the object
file.  See issue 14876 for some examples.  Add a new OBJECT_FILE_DIR
placeholder to specify the directory containing the object file for the
current compilation.  This may differ from the main target OBJECT_DIR
when the object corresponds to a source in a subdirectory.

COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.
