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.

Change the cmGeneratorExpressionEvaluator to invoke
GetLinkImplementationLibraries instead of GetLinkImplementation.

Stephen Kelly 21e91350b0 cmTarget: Change GetTransitivePropertyLinkLibraries to output targets.
The callers already skip non-targets, so unify the target search.

Change supporting functions to accept a container of targets instead
of strings where possible.

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.

This is consistent with other similar expressions such as PLATFORM_ID,

Remove the test for 'bad' nullary use of $<CONFIG>.

the same value.

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.

Brad King d960589778 Genex: Reject $<TARGET_FILE:...> for object libraries (#14532)
Teach the cmGeneratorExpressionEvaluator filesystem artifact logic
to reject OBJECT_LIBRARY targets since they have no main artifact.
Without the explicit rejection evaluation falls through to an
internal CMake error message in cmTarget::GetOutputInfo.

Stephen Kelly c4373b33b2 cmTarget: Make GetProperty() const.
This has follow-on effects for other methods and classes. Further

done, particularly with a view to generate-time methods.

Stephen Kelly ff6c401309 cmTarget: Add interface for compatible numeric properties
When using the boost MPL library, one can set a define to increase
the limit of how many variadic elements should be supported. The
default for BOOST_MPL_LIMIT_VECTOR_SIZE is 20:

 http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/limit-vector-size.html

If the foo library requires that to be set to 30, and the independent
bar library requires it to be set to 40, consumers of both need to set
it to 40.

 add_library(foo INTERFACE)
 set_property(TARGET foo PROPERTY INTERFACE_boost_mpl_vector_size 30)
 set_property(TARGET foo PROPERTY COMPATIBLE_INTERFACE_NUMBER_MAX boost_mpl_vector_size)
 target_compile_definitions(foo INTERFACE BOOST_MPL_LIMIT_VECTOR_SIZE=$<TARGET_PROPERTY:boost_mpl_vector_size>)

 add_library(bar INTERFACE)
 set_property(TARGET bar PROPERTY INTERFACE_boost_mpl_vector_size 40)
 # Technically the next two lines are redundant, but as foo and bar are
 # independent, they both set these interfaces.
 set_property(TARGET bar PROPERTY COMPATIBLE_INTERFACE_NUMBER_MAX boost_mpl_vector_size)
 target_compile_definitions(bar INTERFACE BOOST_MPL_LIMIT_VECTOR_SIZE=$<TARGET_PROPERTY:boost_mpl_vector_size>)

 add_executable(user)
 target_link_libraries(user foo bar)

Because the TARGET_PROPERTY reads the boost_mpl_vector_size property
from the HEAD of the dependency graph (the user target), and because
that property appears in the COMPATIBLE_INTERFACE_NUMBER_MAX of
the dependencies of the user target, the maximum value for it is
chosen for the compile definition, ie, 40.

There are also use-cases for choosing the minimum value of a number.
In Qt, deprecated API can be disabled by version. Setting the
definition QT_DISABLE_DEPRECATED_BEFORE=0 disables no deprecated
API. Setting it to 0x501000 disables API which was deprecated before
Qt 5.1 etc.

If two dependencies require the use of API which was deprecated in
different Qt versions, then COMPATIBLE_INTERFACE_NUMBER_MIN can be
used to ensure that both can compile.

Commit 10a069b5 (Genex: Fix $<CONFIG> with IMPORTED targets and
multiple locations., 2013-07-15) changed the logic here to include
handling of the MAP_IMPORTED_CONFIG_<CONFIG> target property, but
it was buggy in several ways.

Uppercase the configs in all cases, and compare the mapped configs
with the parameter to the CONFIG genex, instead of with the key of
the mapping.

Stephen Kelly 370bf55415 Add the ALIAS target concept for libraries and executables.
* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
  of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
  and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
  target property.
* An ALIAS does not appear in the generated buildsystem. It
  is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.

Stephen Kelly 4f6bd7022b Remove the LINK_LANGUAGE generator expression.
It accepted an optional argument to test for equality, but no way
to get the linker language of a particular target.

the necessary API for equality test.

property of another target.
