Stephen Kelly e1f908015f Don't populate INTERFACE includes and defines properties in tll.
This is a partial revert of commit 77cecb77 (Add includes and compile
definitions with target_link_libraries., 2012-11-05).

As the interface includes and defines are now determined by the link
closure, there is no need to populate the corresponding properties
explicitly.

Stephen Kelly 567c8d103e Revert "Don't allow utility or global targets in the LINKED expression."
This reverts commit 9712362b45.
2013-02-13 15:12:31 +01:00
Stephen Kelly a1c4905f72 Use the link information as a source of compile definitions and includes.
After evaluating the INTERFACE_INCLUDE_DIRECTORIES, of a target in a
generator expression, also read the INTERFACE_INCLUDE_DIRECTORIES of
its link interface dependencies.

That means that code such as this will result in the 'user' target
using /bar/include and /foo/include:

 add_library(foo ...)
 target_include_directories(foo INTERFACE /foo/include)
 add_library(bar ...)
 target_include_directories(bar INTERFACE /bar/include)
 target_link_libraries(bar LINK_PUBLIC foo)

 add_executable(user ...)
 target_include_directories(user PRIVATE
    $<TARGET_PROPERTY:bar,INTERFACE_INCLUDE_DIRECTORIES>)

Also process the interface include directories from direct link
dependencies for in-build targets.

The situation is similar for the INTERFACE_COMPILE_DEFINITIONS. The
include directories related code is currently more complex because
we also need to store a backtrace at configure-time for the purpose
of debugging includes. The compile definitions related code will use
the same pattern in the future.

This is not a change in behavior, as existing code has the same effect,
but that existing code will be removed in follow-up commits.

Stephen Kelly 510fdcb188 Whitelist target types in target_{include_directories,compile_definitions}
Setting include directories or compile definitions on a target created
with add_custom_target does not make sense.
2013-02-08 19:21:30 +01:00
Stephen Kelly 4de71786e8 Ensure that the build interface includes have been added.
This is needed in the case that Automoc is used, as that calls
GetIncludeDirectories, which may cache the resulting include dirs
too early in the generate step.

Also, because the automoc step is so early, we can't cache the
include directories at that point. At that point the build interface
of all dependencies are not populated yet, so we'd be caching the
includes before appending the build interface. Only start caching
when we're definitely generating the buildsystem. At that point, the
includes should be stable.

We still need to invoke AppendBuildInterfaceIncludes
in the GlobalGenerator because the build interface includes affect
mostly the dependencies of targets (such as the automoc targets),
rather than the targets themselves, so the build interface needs
to be appended for all targets before generation is done.

Brad King e3841cf4a2 CTest: Add options to set generator toolset
The ctest_configure command already reads the CTEST_CMAKE_GENERATOR
variable to get the value for the cmake -G option.  Read new variable
CTEST_CMAKE_GENERATOR_TOOLSET for -T.

The "ctest --build-and-test" mode already has "--build-generator" to
specify the -G option to CMake.  Add a "--build-generator-toolset" option
to specify the -T value.

Brad King 650c647160 VS: Implement generator toolset selection (#10722, #13774)
Implement generator toolset selection (cmake -T) for VS >= 10 by setting
the PlatformToolset.  Extend the RunCMake.GeneratorToolset test case to
verify CMAKE_GENERATOR_TOOLSET when the generator supports -T.

Since commit 485a940e (VS: Simplify MSVC version reporting, 2012-08-23)
all MSVC version information is detected during the compiler id step
from the actual compiler invoked by generated build systems rather than
hard-coded in VS generators.  Therefore we can set the PlatformToolset
in VS >= 10 project files and support toolsets from other VS versions.

Brad King 4fd5342956 CMake: Add -T option to choose a generator toolset
Reject the option by default.  It will be implemented on a per-generator
basis.  Pass the setting into try_compile project generation.  Add cache
entry CMAKE_GENERATOR_TOOLSET and associated variable documentation to
hold the value persistently.

Add a RunCMake.GeneratorToolset test to cover basic "-T" option cases.
Verify that CMAKE_GENERATOR_TOOLSET is empty without -T, that -T is
rejected when the generator doesn't support it, and that two -T options
are always rejected.

Stephen Kelly d4e5c6787c 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.

Stephen Kelly 57175d559e Only use early evaluation termination for transitive properties.
We need to make sure expressions which evaluate TARGET_PROPERTY:TYPE

not an empty string instead.

2013-02-07 16:21:09 +01:00
Stephen Kelly 3a298c0bf4 Fix generation of COMPILE_DEFINITIONS in DependInfo.cmake.
As INTERFACE_COMPILE_DEFINITIONS are now possible, we can have
situations like this:

 add_library(foo ...)
 add_library(bar ...)
 target_link_libraries(foo bar)

 target_compile_definitions(bar INTERFACE SOME_DEF)

The INTERFACE_COMPILE_DEFINITIONS of bar determine how foo should be
compiled, and if they change, foo should be rebuilt.

Additionally, as of commit d1446ca7 (Append the COMPILE_DEFINITIONS
from the Makefile to all targets., 2012-09-17), we don't need to
read definitions from the makefile if we read them from the target,
so also de-duplicate the cached info.

The DependInfo for INTERFACE_INCLUDE_DIRECTORIES is already handled
correctly.

Remove the old "nocwd" behavior that attempts to provide the "--help"

scrolls the real error message out of typical terminal sizes.  Also
execute as little code as possible when no working directory exists.

Stephen Kelly 1714c27a74 Process generator expressions for 'system' include directories.
Since commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property., 2012-09-18), it is possible to use
generator expressions with the include_directories command.

As that command can also have a SYSTEM argument, ensure that the
result of using that argument with generator expressions gives a
sane result.
