The other infrastructure for transitive property handling is
already using a preprocessor loop.
Implement special backward-compatibility handling of
COMPILE_DEFINITIONS_<CONFIG> using a template switch for the
extra check.
84fac67 Don't allow include() of export(EXPORT) file at configure time.
faedd2b cmTarget: Fix system include annotation propagation.

10d65d5 cmTarget: Move a variable initialization closer to where it is used.
0f3e8e9 Undefine local preprocessor loop variables.
9ba47ee Genex: Reform error-checking for nullary/unary expressions.
fa651c7 cmTarget: Remove some of the INTERFACE_LIBRARY whitelisted properties.
61d138a cmTarget: INTERFACE_LIBRARY is always EXCLUDE_FROM_ALL.
3429541 export: Rename some variables to reflect content type.
7461d67 cmTarget: Enable convenient include dir handling for INTERFACE_LIBRARY.
7fc6e3d cmTarget: Remove dead code.
2af966d Genex: Add EQUAL expression.
2d66380 cmTarget: Use strtol for numeric parsing.
As a new feature it does not need to participate in CMP0024.
Store cmExportBuildFileGenerator instances which correspond to the
export(EXPORT) signature in a second map which does not own the
pointers. This avoids the need to add cmExportBuildFileGenerator
and dependencies to the bootstrap system.
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.
The error messages were incorrect (reporting that the expression
requires one or two parameters), and repeated. Remove the now-unused
ZeroOrMoreParameters enum value.
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.
Describe how to define a buildsystem of binary targets, how to
express dependencies between them, how to add build specifications,
how to specify usage requirements, transitive and compatible
propagation and the various pseudo targets.
Test that it is an error to read a number-compatible property to
determine the link implementation. An alternative would be to
consider the value to be "0", however, that is too arbitrary
given the use-cases of this feature. Values from this feature may
be used in setting a define, where "0" may have special or invalid
meaning and should be explicit.
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 modern way to create configuration dependent content is using
generator expressions in the main export file. The only non-deprecated
property still generated in the configuration-specific files are
IMPORTED_LOCATION_<CONFIG>
INTERFACE_LIBRARY targets have no location, and no need for those
files.
