Stephen Kelly 42ebb1886f Memoize includes and defines from interface libraries.
This is similar in spirit to commit e48d8420 (Cache context-independent
includes on evaluation., 2013-02-03), but it is needed since commit
a1c4905f (Use the link information as a source of compile definitions
and includes., 2013-02-12), which changed how includes and defines
are determined. As they are now determined through the link interface,
we need to cache the result of evaluating them through that.

In the case of the includes, the result was already being cached
and then immediately disposed. Store the result as a member variable
instead to make use of the caching.

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 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.
2013-02-08 12:54:27 +01:00
Stephen Kelly df74bc34d4 Only append build interface include dirs to particular targets.
We shouldn't set the property on all custom targets.
2013-02-07 21:57:35 +01:00
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.

2013-02-05 09:19:27 +01:00
Stephen Kelly e48d84209c Cache context-independent includes on evaluation.
Generator expressions whose output depends on the configuration
now record that fact. The GetIncludeDirectories method can use
that result to cache the include directories for later calls.

GetIncludeDirectories is called multiple times for a target
for each configuration, so this should restore performance for
multi-config generators.

Stephen Kelly 1da75022bb Don't include generator expressions in old-style link handling.
Don't add generator expressions to variables which are used
for CMP0003, CMP0004, and the old-style _LIB_DEPENDS content. They
will not be evaluated when read anyway and would probably confuse
the code reading them.

This makes it legitimate to use target_link_libraries with generator
expressions as arguments.
2013-01-13 09:59:42 +01:00
Stephen Kelly 77d2646784 Allow generator expressions in LINK_INTERFACE_LIBRARIES.
The Config and IMPORTED_ variants may also contain generator
expressions.

If 'the implementation is the interface', then the result of
evaluating the expressions at generate time is used to populate
the IMPORTED_LINK_INTERFACE_LIBRARIES property.

1) In the case of non-static libraries, this is fine because the
  user still has the option to populate the LINK_INTERFACE_LIBRARIES
  with generator expressions if that is what is wanted.

2) In the case of static libraries, this prevents a footgun,
  enforcing that the interface and the implementation are really
  the same.

  Otherwise, the LINK_LIBRARIES could contain a generator
  expression which is evaluated with a different context at build
  time, and when used as an imported target. That would mean that the
  result of evaluating the INTERFACE_LINK_LIBRARIES property for
  a static library would not necessarily be the 'link implementation'.

  For example:

    add_library(libone STATIC libone.cpp)
    add_library(libtwo STATIC libtwo.cpp)
    add_library(libthree STATIC libthree.cpp)

    target_link_libraries(libtwo
      $<$<STREQUAL:$<TARGET_PROPERTY:TYPE>,STATIC_LIBRARY>:libone>)
    target_link_libraries(libthree libtwo)

  If the LINK_LIBRARIES content was simply copied to the
  IMPORTED_LINK_INTERFACE_LIBRARIES, then libthree links to libone, but
  executables linking to libthree will not link to libone.

3) As the 'implementation is the interface' concept is to be
  deprecated in the future anyway, this should be fine.
2013-01-10 23:04:06 +01:00
Stephen Kelly 3581b96caa Process the INTERFACE_PIC property from linked dependencies
This allows a dependee to inform a target that it should have its
POSITION_INDEPENDENT_CODE property set to ON, or OFF. The value of
the POSITION_INDEPENDENT_CODE property, if set, must be consistent
with any INTERFACE_POSITION_INDEPENDENT_CODE properties on dependees.

Add a test covering the consistency checks on platforms where they run.
2013-01-10 09:54:52 -05:00
Stephen Kelly 042ecf0471 Add API to calculate link-interface-dependent bool properties or error.
This new method checks that the property FOO on a target is consistent
with the INTERFACE_FOO properties of its dependees. If they are not the
consistent, an error is reported. 'Consistent' means that iff the
property is set, it must have the same boolean value as all other
related properties.

Stephen Kelly 7653862798 Add LINK_LIBRARIES property for direct target link dependencies
Previously we kept direct link dependencies in OriginalLinkLibraries.
The property exposes the information in the CMake language through the
get/set_property commands.  We preserve the OriginalLinkLibraries value
internally to support old APIs like that for CMP0003's OLD behavior, but
the property is now authoritative.  This follows up from commit d5cf644a
(Split link information processing into two steps, 2012-11-01).

This will be used later to populate the link interface properties when
exporting targets, and will later allow use of generator expressions
when linking to libraries with target_link_libraries.

Also make targets depend on the (config-specific) union of dependencies.
CMake now allows linking to dependencies or not depending on the config.
However, generated build systems are not all capable of processing
config-specific dependencies, so the targets depend on the union of
dependencies for all configs.
2013-01-08 09:02:43 -05:00
Stephen Kelly 40cf3fb95b Make linking APIs aware of 'head' target
The 'head' is the dependent target to be linked with the current target.
It will be used to evaluate generator expressions with proper handling
of mapped configurations and is used as the source target of properties.

This requires that memoization is done with a key of a pair of target
and config, instead of just config, because now the result also depends
on the target.  Removing the memoization entirely is not an option
because it slows cmake down considerably.

Stephen Kelly bd34963002 Refactor generation of shared library flags
CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a
variety of purposes that are correlated with shared libraries but not
exclusive to them.  Refactor generation of these flags to use new
purpose-specific platform variables

  CMAKE_<lang>_COMPILE_OPTIONS_DLL
  CMAKE_<lang>_COMPILE_OPTIONS_PIC
  CMAKE_<lang>_COMPILE_OPTIONS_PIE

Activate the DLL flags specifically for shared libraries.  Add a new
POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and
default to true for shared libraries to preserve default behavior.
Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to
allow easy global configuration in projects.

Although the default behavior is unchanged by this refactoring, the new
approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely.  We must
leave it set in case projects reference the value.  Furthermore, if a
project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new
value to be used.  Add policy CMP0018 to handle compatibility with
projects that modify this platform variable.

Add a PositionIndependentCode test on platforms where we can get
meaningful results.

Modestas Vainius 1aa52163ef Fix a few typos in NO_SONAME property description. 2012-05-02 15:14:05 -04:00
Modestas Vainius e1409ac59b Support building shared libraries or modules without soname (#13155)
Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it.  This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.

Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question.  Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it.  Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded.  Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well.  Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.

The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders.  Final substitution is
performed by ninja at build time.  Therefore we cannot conditionally
replace the soname placeholders on a per-target basis.  Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME.  Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.

Brad King b87d7a60a0 Add OBJECT_LIBRARY target type
This library type can compile sources to object files but does not link
or archive them.  It will be useful to reference from executable and
normal library targets for direct inclusion of object files in them.

Diagnose and reject the following as errors:

* An OBJECT library may not be referenced in target_link_libraries.

* An OBJECT library may contain only compiling sources and supporting
  headers and custom commands.  Other source types that are not normally
  ignored are not allowed.

* An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD
  commands.

* An OBJECT library may not be installed, exported, or imported.

Some of these cases may be supported in the future but are not for now.

Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just
like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.

For now, CMAKE_XCODE_EFFECTIVE_PLATFORMS must be defined in each

of CMake.  The property is documented as provided only for compatibility
with CMake 2.4 and alternative interfaces are now available for all
originally envisioned use cases.  We want to discourage its use without
outright deprecating it.  Add documentation to explicitly state that
reading the property before other properties are set is undefined.

Brad King f0cdb6001b Introduce "generator expression" syntax to custom commands (#11209)
Evaluate in the COMMAND arguments of custom commands the generator
expression syntax introduced in commit d2e1f2b4 (Introduce "generator
expressions" to add_test, 2009-08-11).  These expressions have a syntax
like $<TARGET_FILE:mytarget> and are evaluated during build system
generation.  This syntax allows per-configuration target output files to
be referenced in custom command lines.

Brad King 3b7f901494 Fix soname in cross-compiled targets with Mac host (#11547)
The soname generation code was compile-time selected instead of runtime
selected.  The result is that a Mac-compiled cmake used to cross-compile
Mac -> Unix generates an soname of the form libfoo.x.y.so instead of
libfoo.so.x.y as expected.  Instead do a runtime check based on the
target platform.

Brad King 608d6bba89 Fix parallel "make install" of CMake itself
Avoid tracing dependencies of GLOBAL_TARGET targets.  The build system
generators are not designed to handle any dependencies that may be
discovered.  Global targets are only generated by CMake and never have
commands that reference targets built in the project anyway.

The exception is when building CMake itself there is a special case to
use the just-built "cmake" binary in the "install" target so that CMake
can replace itself on Windows.  Even in this special case we do not want
to let the "install" target depend on the "cmake" target.  Doing so
breaks cases like "make -j4 install".

David Cole e6ac0aacf6 Add FOLDER target property, for IDEs (#3796)
This work was started from a patch by Thomas Schiffer.
Thanks, Thomas!

See the newly added documentation of the FOLDER target
property for details.

Also added global properties, USE_FOLDERS and
PREDEFINED_TARGETS_FOLDER. See new docs here, too.

By default, the FOLDER target property is used to organize
targets into folders in IDEs that have support for such
organization.

This commit adds "solution folder" support to the Visual
Studio generators. Currently works with versions 7 through
10.

Also, use the new FOLDER property in the ExternalProject
test and in the CMake project itself.

Cygwin versions .dll files by putting the version number in the file

Brad King 74c59a748d Introduce per-config OUTPUT_DIRECTORY properties
We create per-configuration target properties to specify ARCHIVE,
LIBRARY, and RUNTIME output directories.  The properties override the
generic properties for the <CONFIG> configuration:

  ARCHIVE_OUTPUT_DIRECTORY -> ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
  LIBRARY_OUTPUT_DIRECTORY -> LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
  RUNTIME_OUTPUT_DIRECTORY -> RUNTIME_OUTPUT_DIRECTORY_<CONFIG>

For multi-configuration generators, the per-configuration subdirectory
normally appended to the generic output directory is not added to the
configuration-specific property values.  This allows projects to set the
exact location at which binaries will be placed for each configuration.

See issue #9163.

Brad King 02f85f98c6 Target copy ctor should copy internal state
Ideally we should never copy cmTarget instances, but it is a pain to

Brad King 0fb5b2c88c Invalidate target link info when necessary
In cmTarget we compute the link implementation, link interface, and link

or a new link library is added.  We also clear the results at the end of
the Configure step to ensure the Generate step uses up-to-date results.

during its analysis.  Later this can be used by generators that need to
topologically order custom command rules.
2009-09-07 10:11:43 -04:00
Brad King 368a18b83c Cleanup source file dependency tracing logic
In cmTarget we trace the dependencies of source files in the target to
bring in all custom commands needed to generate them.  We clean up the
implementation to use simpler logic and better method names.  The new
approach is based on the observation that a source file is actually an
input (dependency) of the rule that it runs (compiler or custom) even in
the case that it is generated (another .rule file has the rule to
generate it).

times a linker should scan through a mutually dependent group of static
libraries.  The largest value of this property on any target in the
group is used.  This will help projects link even for extreme cases of
cyclic inter-target dependencies.

Brad King 463b3f03bd Create cmTarget DLL query methods

executables with exports.

Brad King fcab87c9f8 Do not always propagate linker language preference
The commit "Consider link dependencies for link language" taught CMake
to propagate linker language preference from languages compiled into
libraries linked by a target.  It turns out this should only be done for
some languages, such as C++, because normally the language of the
program entry point (main) should be used.

We introduce variable CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES to tell
CMake whether a language should propagate its linker preference across
targets.  Currently it is true only for C++.

Brad King 19792bf30e ENH: Consider link dependencies for link language
This teaches cmTarget to account for the languages compiled into link
dependencies when determining the linker language for its target.

We list the languages compiled into a static archive in its link
interface.  Any target linking to it knows that the runtime libraries
for the static archive's languages must be available at link time.  For
now this affects only the linker language selection, but later it will
allow CMake to automatically list the language runtime libraries.

Brad King 99e432508e BUG: Use link language for target name computation
The commit "Do not compute link language for LOCATION" was wrong.  The
variables

  CMAKE_STATIC_LIBRARY_PREFIX_Java
  CMAKE_STATIC_LIBRARY_SUFFIX_Java

are used for building Java .jar files.  This commit re-enables the
feature and documents the variables:

  CMAKE_EXECUTABLE_SUFFIX_<LANG>
  CMAKE_IMPORT_LIBRARY_PREFIX_<LANG>
  CMAKE_IMPORT_LIBRARY_SUFFIX_<LANG>
  CMAKE_SHARED_LIBRARY_PREFIX_<LANG>
  CMAKE_SHARED_LIBRARY_SUFFIX_<LANG>
  CMAKE_SHARED_MODULE_PREFIX_<LANG>
  CMAKE_SHARED_MODULE_SUFFIX_<LANG>
  CMAKE_STATIC_LIBRARY_PREFIX_<LANG>
  CMAKE_STATIC_LIBRARY_SUFFIX_<LANG>

Instead of making separate, repetitive entries for the _<LANG> variable
documentation, we just mention the per-language name in the text of the
platform-wide variable documentation.  Internally we keep undocumented
definitions of these properties to satisfy CMAKE_STRICT mode.

Brad King 2b5d97419f ENH: Do not compute link language for LOCATION
The LOCATION property requires the full file name of a target to be
computed.  Previously we computed the linker language for a target to
look up variables such as CMAKE_SHARED_LIBRARY_SUFFIX_<LANG>.  This led
to locating all the source files immediately instead of delaying the
search to generation time.  In the future even more computation will be
needed to get the linker language, so it is better to avoid it.

The _<LANG> versions of these variables are undocumented, not set in any
platform file we provide, and do not produce hits in google.  This
change just removes the unused feature outright.

Brad King 392b38cef7 ENH: Remove cmTarget internal type arguments
Internally cmTarget was passing the target type in several name

so this change simplifies the internals by using the GetType method and
dropping the type from method signatures.

Brad King 430cc2b4b7 ENH: Always imply CLEAN_DIRECT_OUTPUT target prop
This property was left from before CMake always linked using full path
library names for targets it builds.  In order to safely link with
"-lfoo" we needed to avoid having both shared and static libraries in
the build tree for targets that switch on BUILD_SHARED_LIBS.  This meant
cleaning both shared and static names before creating the library, which
led to the creation of CLEAN_DIRECT_OUTPUT to disable the behavior.

Now that we always link with a full path we do not need to clean old
library names left from an alternate setting of BUILD_SHARED_LIBS.  This
change removes the CLEAN_DIRECT_OUTPUT property and instead uses its
behavior always.  It removes some complexity from cmTarget internally.
2009-05-01 10:38:35 -04:00
Brad King 2740db5ede ENH: Allow more specification of target file names
This creates target properties ARCHIVE_OUTPUT_NAME, LIBRARY_OUTPUT_NAME,

ARCHIVE_OUTPUT_NAME_<CONFIG>, LIBRARY_OUTPUT_NAME_<CONFIG>, and
RUNTIME_OUTPUT_NAME_<CONFIG>.  They allow specification of target output
file names on a per-type, per-configuration basis.  For example, a .dll
and its .lib import library may have different base names.

For consistency and to avoid ambiguity, the old <CONFIG>_OUTPUT_NAME
property is now also available as OUTPUT_NAME_<CONFIG>.
