Stephen Kelly e3b5eb6b23 Automatically link to the qtmain library when linking to QtCore.
When using QAxServer, ensure that the qtmain library is excluded
by reporting an error at CMake time if it is not.

Stephen Kelly e98799105b Make INTERFACE determined properties readable in generator expressions.
The properties are evaluated as link-dependent interface properties when
evaluating the generator expressions.
2013-01-20 17:06:47 +01:00
Stephen Kelly 6c8d8afe34 Add the $<TARGET_POLICY> expression
This new expression allows checking how a policy was set when a target
was created.  That information is only recorded for a subset of policies,
so a whitelist is used.

Stephen Kelly 2bee6f5ba5 Add the TARGET_DEFINED generator expression
This tests whether the parameter is a usable target.

Stephen Kelly bf5ece51c3 Keep track of properties used to determine linker libraries.
Those properties can't later be implicitly defined by the interface
of those link libraries.

Stephen Kelly 894f52f32d Handle INTERFACE properties transitively for includes and defines.
Contextually, the behavior is as if the properties content from another
target is included in the string and then the result is evaluated.

Stephen Kelly c67b8124f7 Make cycles in target properties ignored, not an error.
Constructs such as these are an error as they are direct self-references:

 set_property(TARGET foo APPEND PROPERTY
   INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>)
 set_property(TARGET foo APPEND PROPERTY
   INCLUDE_DIRECTORIES $<TARGET_PROPERTY:INCLUDE_DIRECTORIES>)

However, this is an indirect self-reference in a cycle, and not an error:

 set_property(TARGET foo APPEND PROPERTY
   INCLUDE_DIRECTORIES $<TARGET_PROPERTY:bar,INCLUDE_DIRECTORIES>)
 set_property(TARGET bar APPEND PROPERTY
   INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>)

Stephen Kelly 26def1771d Make all relevant targets available in the genex context.
The current node being evaluated transitively in the generator
expression must be available to resolve mapped configs.

Stephen Kelly b0c8f73eb6 Add the TARGET_NAME generator expression.
It will be used as a preprocessing marker.

Stephen Kelly b2f1700bc7 GenEx: Add expressions to specify build- or install-only values
This is for specifying INCLUDE_DIRECTORIES relevant to the build-location
or the install location for example:

 set_property(TARGET foo PROPERTY
   INTERFACE_INCLUDE_DIRECTORIES
   "$<BUILD_INTERFACE:${CMAKE_CURRENT_BINARY_DIR};${CMAKE_CURRENT_SOURCE_DIR}>"
   "$<INSTALL_INTERFACE:${CMAKE_INSTALL_PREFIX}/include>"
 )

A 'bar' target can then use:

 set_property(TARGET bar PROPERTY
   INCLUDE_DIRECTORIES
   "$<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>"
 )

and it will work whether foo is in the same project, or an imported target
from an installation location, or an imported target from a build location
generated by the export() command.

Because the generator expressions are only evaluated at build-time, these
new expressions are equivalent to the ZeroNode and OneNode.

The GeneratorExpression test is split into parts. Some shells can't run
the custom command as it is getting too long.

Stephen Kelly d8a59ea4b3 Port cmGeneratorExpression to cmTarget from cmGeneratorTarget.
Following from the discussion here:

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/3615/focus=5170
 (Re: Generator expressisons in target properties, 26 Oct 12:10)

we can't split cmTarget API for linking into cmGeneratorTarget. In
the future we will probably also need to move the include and compile
definitions API back to cmTarget so that it can be used by export().

Stephen Kelly a573a85658 Attempt to fix the compile of cmake on Sun CC.
The problem may be that the reportError method is static, so make
it non-static on that platform.

Stephen Kelly eb250cd18a Add a self-reference check for target properties.
Prevent constructs like:

 ... INCLUDE_DIRECTORIES "$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>"

Indirect self-references (cycles) are also prevented here, but
indirect generator expression references of any kind are not
possible yet anyway.

Stephen Kelly 7e807472d2 Add API to check that dependent target properties form a DAG.
Initially this will only be used to check for self-references, but
can be extended to check for cycles when chaining properties of other
targets.
2012-09-28 08:49:21 -04:00
Stephen Kelly 239ac84153 Add a generator expression for target properties.
There are two overloads, so that it can use the operational
target when a target property is being evaluated, and a target
can alternatively be specified by name.

At this point, the generators don't chain. That comes later.

Stephen Kelly e028381bf1 Extend the generator expression language with more logic.

and commas are added. Those may be needed in some cases
where they appear in literals.

Stephen Kelly f1eacf0e07 cmGeneratorExpression: Re-write for multi-stage evaluation
The expressions may be parsed and then cached and evaluated multiple
times.  They are evaluated lazily so that literals such as ',' can be
treated as universal parameter separators, and can be processed from
results without appearing literally, and without interfering with the
parsing/evaluation of the entire expression.
