Stephen Kelly e6971df6ab cmTarget: Make the source files depend on the config.
Disallow the use of config-specific source files with
the Visual Studio and Xcode generators. They don't have
any way to represent the condition currently.

Use the same common-config API in cmQtAutoGenerators. While
it accepts config-specific files, it doesn't have to support
multiple configurations yet.

Loop over the configs in cmTargetTraceDependencies
and cmGlobalGenerator::WriteSummary and consume all source
files.

Loop over the configs in cmComputeTargetDepends and compute the
object library dependencies for each config.

Stephen Kelly aa0a3562dd cmGeneratorTarget: Compute target objects on demand
Add a ComputeObjectMapping method to compute the object
names.  It takes mapping to populate as an out-parameter so
that it can be extended in the future with parameters
relevant to generator expression evaluation.

Remove the supporting cmGeneratorTarget::AddObject method. It is
no longer needed as the container member is populated directly.

The ComputeObjectMapping method is called whenever objects are
requested from the cmGeneratorTarget.  Because the Xcode generator
makes no such request, explicitly invoke the method from that
generator so that the logic of checking for bad sources in object
libraries is executed.

In a follow-up, the UseObjectLibraries usage may be replaced by a
true generator expression evaluator for TARGET_OBJECTS. That
will require generators to use cmGeneratorTarget::GetExternalObjects
which is not currently the case for Xcode and VS generators.

Stephen Kelly fdcefe3c42 cmGeneratorTarget: Compute consumed object libraries on demand.
Remove up-front object library computation from cmGlobalGenerator.

evaluation.

Brad King 8018fcca6e Merge branch 'master' into revise-compiler-id-policies 2014-04-02 14:44:35 -04:00
Brad King a41c0a9dcb Do not warn by default when policy CMP0025 or CMP0047 is not set
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project.  Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.

This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior.  When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.

Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Stephen Kelly 64d398416a cmGeneratorTarget: Classify sources on demand, not up front.
Implement a Visitor to hold the sequence of source file tests
for populating outputs.  Use VS 6 and 7 workaround from Brad
King for lack of partial template specialization and function
template specialization capabilities.

This will make it possible to use context dependent generator
expressions to determine the sources of a target.

Stephen Kelly f81eb49e8b cmTarget: Find source files on request.
In a follow-up, the list of sources will become dependent on

Clinton Stimpson 028a5285d8 OS X: Make sure RPATHs are unique to avoid possible corruption.
When using link_directories() and including CMAKE_CFG_INTDIR,
one can end up with duplicate RPATHs in the binary which
install_name_tool cannot fix without corrupting the binary.
Also, the cmake_install.cmake file has been fixed to correctly
handle these generator specific variables.

Stephen Kelly e00db59d6c QNX: Introduce QCC compiler id for that QNX platform compiler.
Introduce policy CMP0047 to control resetting the id for
compatibility.

De-duplicate content in the QNX platform file by including the GNU
one. QNX is a form of GNU platform.

Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables.  They
are populated again later by the Compiler/GNU.cmake file anyway.

Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC
compiler id is in use, and the language is CXX.  Use the QNX
recommended flag for QCC instead of the gcc compatible -x flag.

Populate new module files to handle system includes and depfiles
when using the QCC compiler.

Remove code which unsets the system include and depfiles related
variables.  When a GNU driver is used instead of the QCC one, the
appropriate flags will be used.  These variables were previously
cleared for lowest-common-denominator compatibility with both
drivers.

Stephen Kelly faedd2bea9 cmTarget: Fix system include annotation propagation.
Direct users of IMPORTED targets treat INTERFACE_INCLUDE_DIRECTORIES
as SYSTEM, after commit a63fcbcb (Always consider includes from IMPORTED
targets to be SYSTEM., 2013-08-29).  It was intended that transitive
use of an IMPORTED target would have the same behavior, but that
did not work.  The implementation processed only direct dependencies
in cmTarget::FinalizeSystemIncludeDirectories.

Implement transitive evaluation of dependencies by traversing the
link interface of each target in the link implementation.
