Restore support for the undocumented <CONFIG>_LOCATION target property
removed by commit v3.0.0-rc1~175^2 (cmTarget: Remove support for
<CONFIG>_LOCATION property, 2013-12-30) as part of the CMP0026 OLD
behavior.
It accepts a before parameter but is never called with before=true.
compile definitions are sorted by std::set, so it wouldn't make sense
to allow user sorting.
Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.
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.
There is no need to allow EXCLUDE_* properties, because an
INTERFACE_LIBRARY has no direct build output.
IMPORTED_LINK_INTERFACE_LANGUAGES are relevant only to static
libraries.
VERSION is relevant only to the filename of direct build outputs,
which INTERFACE_LIBRARY does not have.
If the dependent target sets the property to boolean false, ensure
that that appears in the debug report. Previously, the report
output contained whether the property was consistent among dependencies,
displaying 'TRUE', instead of the content of the property, which may
be 'FALSE'.
Return a std::pair from the consistentProperty method. This makes
it possible to make the return value for string types easier to
reason about. The return value of consistentProperty was previously
set to an empty static string to emulate a 'true' value for the caller
in commit 816b4a8a (cmTarget: Make consistentProperty
return consistent content., 2013-10-22). The pair makes the
consistency result properly typed.
Don't refer to 'both', but a 'mixture'. List all compatible interface
property types possible.
Add another test for a mixture of three compatibilities.
The include_directories() and add_compile_options() commands
should not append to the corresponding target property for IMPORTED
targets. This is already the case for add_definitions().
The INTERFACE_LIBRARY type does not have any LOCATION at all, so
return early from GetMappedConfig. GetMappedConfig is called from
two locations, one of which already pre-checks the INTERFACE_LIBRARY
case. Remove that pre-check and handle that case inside the method
instead.
77f3772 cmTarget: Require a compatible INTERFACE_AUTOUIC_OPTIONS from dependencies.
2e60b5f cmTarget: Report origin of COMPATIBLE_INTERFACE properties.
Revert the origin-tracking infrastructure from commit 98093c45 (QtAutoUic:
Add INTERFACE_AUTOUIC_OPTIONS target property., 2013-11-20). Use the
compatibility-tracking for compatible strings instead.
If two different dependencies require different AUTOUIC_OPTIONS,
cmake will now appropriately issue an error.
Targets which link directly to themselves should not result in
generate-time errors (reported by the DAG checker).
Self-links are handled separately with policy CMP0038.
Transitively consume the property from linked dependents.
Implement configuration-specific support by following the pattern
set out for compile definitions and includes in cmQtAutoGenerators.
Implement support for origin-tracking with CMAKE_DEBUG_TARGET_PROPERTIES.
This is motivated by the needs of KDE, which provides a separate
translation system based on gettext instead of the Qt linguist
translation system. The Qt uic tool provides command line options
for configuring the method used to translate text, and to add an
include directive to the generated file to provide the method.

Implement the interface to provide the uic options as a usage-requirement
on the KI18n target, as designed for KDE.
As an INTERFACE_LIBRARY has no direct link dependencies, we can
short-circuit in cmGeneratorExpressionEvaluator and
in cmGlobalGenerator::CheckLocalGenerators.
As they do not generate any output directly, any generate- or install-
related code acn also be short-circuited. Many of the local generators
already do this.
Because only INTERFACE related properties make sense on INTERFACE_LIBRARY
targets, avoid setting other properties, for example via defaults.
