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.

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.

#include "cmGeneratorExpressionDAGChecker.h"
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.

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.

Don't keep track of content determined by target property values. This tracking was added during the development of commit 042ecf04 (Add API to calculate link-interface-dependent bool properties or error., 2013-01-06), but was never used. It was not necessary to use the content because what is really useful in that logic is to determine if a property has been implied to be null by appearing in a LINK_LIBRARIES genex. I think the motivating usecase for developing the feature of keeping track of the targets relevant to a property was that I thought it would make it possible to allow requiring granular compatibility of interface properties only for targets which depended on the interface property. Eg: add_library(foo ...) add_library(bar ...) add_executable(user ...) # Read the INTERFACE_POSITION_INDEPENDENT_CODE from bar, but not # from foo: target_link_libraries(user foo $<$<TARGET_PROPERTY:POSTITION_INDEPENDENT_CODE>:bar>) This obviously doesn't make sense. We require that INTERFACE properties are consistent across all linked targets instead.

// will check this to ensure that properties have one consistent
// value for all evaluations.

Optimize genex evaluation for includes and defines. While porting boost to use these features, the generation step took too long (several minutes before I stopped it). The reason was that the boost libraries form a large interdependent mesh. The libraries list their dependencies in their INTERFACE such as: $<LINKED:boost::core>;$<LINKED:boost::config>;$<LINKED:boost::mpl> As boost::core already depends on the boost::config libraries, that expression has no impact on the end-content, as it is removed after the generation step. There is no DAG issue though, so the generator expression evaluation would fully evaluate them. In the case of the config library, it also depends on the core library, so all depends are followed through that again, despite the fact that they've just been evaluated. After this patch, the evaluation skips libraries if they have already been seen via depends or directly in the content. This patch keeps track of targets whose INTERFACE has been consumed already. The INCLUDE_DIRECTORIES and COMPILE_DEFINITIONS properties are whitelisted because repeated content will be stripped out later during generation. For other properties now and in the future, that may not be the case.

Genex: Fix the HEAD target used for evaluated expressions If the expression $<TARGET_PROPERTY:prop> appears in the content of a target property, the target that prop is read from is the 'head target' of the expression. In contexts such as evaluating the content of a target property during generation, such as INCLUDE_DIRECTORIES, the 'head target' is the one on which the initial request was made. If evaluating a generator expression which is not a target property content, the target must be explicitly specified. Such contexts include add_custom_command and file(GENERATE). The content might then look like $<TARGET_PROPERTY:tgt,prop> However, as there is no HeadTarget set, any generator expressions evaluated as part of reading prop from tgt which do not specify the tgt directly report an error. Modify the logic of the TARGET_PROPERTY generator expression so that in such contexts, the 'head target' is set to the appropriate target which was first encountered.

The situation is similar for the INTERFACE_COMPILE_DEFINITIONS.

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.
