In cmGeneratorExpressionEvaluator, teach getLinkedTargetsContent to call

Brad King 60bafeb684 Genex: Avoid repeated search of transitive property whitelist
In cmGeneratorExpressionEvaluator, avoid searching through the list of
transitive interface property names repeatedly during evaluation of
TargetPropertyNode.  Simply record the results of the first search for
later re-use.

Brad King 8cb9105431 Genex: Simplify TARGET_PROPERTY transitive lookup
In cmGeneratorExpressionEvaluator, make getLinkedTargetsContent a
template so it can traverse over either the Libraries in a cmTarget
LinkImplementationLibraries or a cmTarget LinkInterfaceLibraries.  This
also avoids creating a separate vector<cmTarget*>.

Brad King 535fd6ce6d cmTarget: Make GetLink*Libraries methods safer to use
Split the library lists out of LinkImplementation and LinkInterface into
LinkImplementationLibraries and LinkInterfaceLibraries parent classes,
respectively.  Return these from GetLinkImplementationLibraries and
GetLinkInterfaceLibraries, respectively, so that callers cannot access
parts of the structures that have not been populated.

Brad King affe9d56a2 Allow INTERFACE_SOURCES to specify $<TARGET_OBJECTS> (#14970)
Fix cmTarget::GetSourceFiles to set EvaluateForBuildsystem on the
$<TARGET_PROPERTY:...,INTERFACE_SOURCES> generator expression so that
the $<TARGET_OBJECTS> generator expression is allowed within an
INTERFACE_SOURCES value.

Extend the InterfaceLibrary test to cover this case.  Extend the
RunCMake.TargetObjects test to cover failure of $<TARGET_OBJECTS>
when used through $<TARGET_PROPERTY:...,INTERFACE_SOURCES> in a
non-buildsystem context.

Brad King 848c8ccf18 cmTarget: Refactor LinkImplementation to allow more information
Create a cmLinkImplItem class derived from cmLinkItem so more

hold it.  Update client sites accordingly.

Stephen Kelly 61ce654742 Genex: Fix stack overflow in transitive property evaluation.
Commit v2.8.11~156^2~2 (Expand includes and defines transitively
in 'external' genexes., 2013-02-13) introduced a recursive loop
and a stack overflow during evaluation of a link implementation
which depends on a transitive property, such as

 add_library(empty1 ...)
 add_library(empty2 ...)
 target_link_libraries(empty1
   PRIVATE
     $<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2>
 )

There is no use-case for code like that currently, but it should not
cause a stack overflow.

Avoid the recursion by reporting an error early if a case like this
is found.

Brad King d912220eaa cmTarget: Lookup targets in LinkInterface and LinkImplementation
Instead of storing just the string names in these structures, lookup any
target associated with each item and store its cmTarget pointer.  Use
the cmLinkItem class to hold the name and pointer together.  Update
client sites to use the pre-stored lookup result instead of looking up
the target name again.

Create a cmTarget::LookupLinkItems helper method to handle the lookup.
Since lookups are now moving from cmComputeLinkDepends::AddLinkEntries
to cmTarget::LookupLinkItems, move use of CheckCMP0004 to the latter.
This drops use of CheckCMP0004 from entries added for _LIB_DEPENDS
variables by cmComputeLinkDepends::AddVarLinkEntries, but I do not
think that use was intentional originally anyway.

Brad King a272344228 Fix scope of transitive target name lookups
In cmTarget, cmGeneratorTarget, and cmGeneratorExpressionEvaluator, fix
target name lookups to occur in the cmMakefile context of the target
that referenced the name, not the current 'head' target.  The context
matters for imported targets because they are directory-scoped instead
of globally unique.  We already do this in cmComputeLinkDepends and
cmComputeTargetDepends.

Extend the InterfaceLibrary test with an example covering this behavior.

Brad King 0dc9e88d76 cmTarget: Remove 'head' argument from GetLinkImplementation
Many of the 'head' arguments added by commit v2.8.11~289^2~1 (Make
linking APIs aware of 'head' target, 2013-01-04) turned out not to be
needed.  The "link implementation" of a target never needs to be
computed with anything but itself as the 'head' target (except for
CMP0022 OLD behavior because then it is the link interface).

Remove the unused 'head' target paths.  Add "internal" versions of
cmTarget::GetDirectLinkLibraries and GetLinkImplementationLibraries
to support the CMP0022 OLD behavior without otherwise exposing the
'head' target option of these methods.

Stephen Kelly 0dfe395e3c Features: Add COMPILE_FEATURES generator expression.
Allow setting build properties based on the features available
for a target.  The availability of features is determined at
generate-time by evaluating the link implementation.

Ensure that the <LANG>_STANDARD determined while evaluating
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.

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 5de63265e3 Genex: Only evaluate TARGET_OBJECTS to determine target sources.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc.  To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.

This commit may be reverted in the future if a solution to the
above difference is implemented.

Stephen Kelly b8b99cc1e5 cmTarget: Avoid computing languages when computing transitive targets.
For the OLD CMP0022 behavior, we need to treat the implementation
as the interface when computing the interface libraries.  Make it
possible to do that without computing the link languages by adding
a new GetLinkImplementationLibraries method.  Extend the existing
GetLinkImplementation method to populate the languages if the
libraries have already been computed and cached.

Change GetTransitivePropertyTargets to invoke GetLinkInterfaceLibraries
instead of GetLinkInterface.  This is key, as it is a method called
by cmGeneratorExpressionEvaluator.

GetLinkImplementationLibraries instead of GetLinkImplementation.

Rolf Eike Beer c768e398f9 cmMakefile: make some methods take const std::string& instead of const char*
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.

Stephen Kelly d36b489401 Genex: Allow single param expressions to accept arbirary input.
Existing single-parameter expressions work due to special casing
which assumes that if there is only one parameter, and the node
accepts arbitrary content, then the result is the input.

This is true for the existing expressions matching that
pattern - namely the "1" and "TARGET_NAME" expressions. However,
the LOWER_CASE, and UPPER_CASE expressions should also accept
arbitrary content, and in their case, the result is not the input.

Refactor the cmGeneratorExpressionEvaluator to allow that extension.
Actually evaluate the "1" and "0" nodes.

Stephen Kelly 0bfcb450e6 INTERFACE_LIBRARY: Avoid codepaths which set unneeded properties.
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.
