ae62a1c Test CMAKE_GNUtoMS option in ExportImport on MinGW and MSys
afb00fe Add CMAKE_GNUtoMS option to convert GNU .dll.a to MS .lib
61e8629 Factor makefile generator link rule lookup into helper function
a603250 Load platform files that need to know the ABI when possible
ecd8414 Fortran: Detect pointer size in gfortran on MinGW
Teach the Windows-GNU.cmake platform file to look for Visual Studio
tools matching the target ABI. Add an extra step to the link command
for shared libraries and executables that export symbols and on which a
new GNUtoMS property is set (initialized by the CMAKE_GNUtoMS option).
Tell the GNU linker to output a module definition (.def) file listing
exported symbols in addition to the GNU-format import library (.dll.a).
Pass the .def file to the MS "lib" tool to construct a MS-format DLL
import library (.lib).
Teach the install(TARGETS) command to install the MS import library next
to the GNU one. Teach the install(EXPORT) and export() command to set
the IMPORTED_IMPLIB property pointing at the import library to use the
import library matching the tools in the importing project.
VS_GLOBAL_PROJECT_TYPES: A string containing UUIDs to embed in the
Visual Studio project file under <ProjectTypes>.
VS_GLOBAL_KEYWORD: Allows specification of a keyword like "ManagedCProj"
instead of the default "Win32Proj", under <Keyword>
VS_DOTNET_REFERENCES: Semicolon-delimited list of .NET references to add
to the project, which creates a new <ItemGroup>.
This commit adds a new target property AUTOMOC_MOC_OPTIONS, which
can be set to add extra options for the moc invocations done via automoc.
This is equivalent to the OPTIONS parameter in the qt4_wrap_cpp() macro.

Define variable CMAKE_LINK_INTERFACE_LIBRARIES to initialize the
value of this property when a target is created. This allows authors
to write
set(CMAKE_LINK_INTERFACE_LIBRARIES "")
to disable transitive linking to implementation dependencies of shared
libraries on platforms where it is possible.
Make it a static method instead of an array. It is safer for the
type checking and if we add a new target type we will be warned to add
a case to the switch.
Caveats apply: only valid when not overriding default value for output
dir *and* there is a CMAKE_XCODE_EFFECTIVE_PLATFORMS value.
For now, CMAKE_XCODE_EFFECTIVE_PLATFORMS must be defined in each
project, or in the cache for a build.
Code relying on value of LOCATION and similar properties may not
work if it depends on file existence on disk since CMake will not
evaluate $(EFFECTIVE_PLATFORM_NAME). This feature is only enabled
for making it easier to build Xcode iOS projects where the developer
wants to be able to switch easily between simulator and device builds.
Define a "Fortran_FORMAT" target and source file property. Initialize
the target property from a "CMAKE_Fortran_FORMAT" variable. Interpret
values "FIXED" and "FREE" to indicate the source file format. Append
corresponding flags to the compiler command line.
Thanks to Pau Garcia i Quiles for the inspiration for the patch.
I've tweaked it a bit compared to what's in the bug tracker: this
commit does not allow empty global variable names.
I also added usage of the new feature to an existing test. Although
it has no effect on the resulting Visual Studio projects, you can
verify that the VSResource test produces a non-empty globals section
in the generated .vcproj(x) files.
set_property() has APPEND, which creates a list. E.g. when
appending to COMPILE_FLAGS a string is needed, not a list.
With the APPEND_STRING option the value is append as string,
not as list.

Avoid GCC warning
warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]
added by commit c6a8e4c7 (The link interface of MODULE libraries is
empty, 2011-03-09).
MODULE libraries cannot be linked into other libraries and executables
(just like executables without ENABLE_EXPORTS). Set the MODULE target
link interface to be empty. This allows such targets to be installed in
an EXPORT set without including all their private implementation
dependencies.
Commit afd7d4ca (Add target property LINK_SEARCH_END_STATIC, 2008-01-31)
defined a property to ensure that static runtime libraries get selected.
Add a property to specify that all libraries whose type is unknown, such
as "-lm", should be assumed static. Furthermore it assumes that an
option such as "-static" is also used so that no initial -Bstatic is
needed.
Although the LOCATION property is for compatibility with CMake 2.4, the
LOCATION_<CONFIG> property is modern. However, if a project reads it
and sets location-altering properties later the behavior is undefined.
See parent commit for details.
Reading the LOCATION target property currently locks down the result and
ignores any later changes to properties that affect it. This may or may
not be expected and may or may not be the behavior in earlier versions
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.

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.
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.

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".
Imported targets do not themselves build, but we can follow dependencies
through them to find real targets. This allows imported targets to
depend on custom targets that provide the underlying files at build
time.
Factor out reading of CMAKE_CONFIGURATION_TYPES and CMAKE_BUILD_TYPE
into cmMakefile::GetConfigurations. Read the former only in
multi-config generators.
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
name. Our fix to issue #3571 taught CMake to do this, but it used the
VERSION target property. It is better to use the SOVERSION property
since that is the interface (rather than implementation) version.
Change based on patch from issue #10122.
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.
The CMAKE_OSX_ARCHITECTURES variable works only as a global setting.
This commit defines target properties
OSX_ARCHITECTURES
OSX_ARCHITECTURES_<CONFIG>
to specify OS X architectures on a per-target and per-configuration
basis. See issue #8725.
The commit "Target copy ctor should copy internal state" created a new
cmTargetInternals constructor but failed to initialize a POD member that
the original constructor initializes. This commit fixes it.
Ideally we should never copy cmTarget instances, but it is a pain to
remove current uses of it. The pimplized portion of cmTarget has mostly
members that cache results, but some are part of the object state.
These should be copied in the copy ctor instead of re-initialized.
In cmTarget we compute the link implementation, link interface, and link
closure structures on-demand and cache the results. This commit teaches
cmTarget to invalidate results after a LINK_INTERFACE_* property changes
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.
In cmTarget::SetProperty and cmTarget::AppendProperty we check whether
changing the property invalidates cached information. The check was
duplicated in the two methods, so this commit moves the check into a
helper method called from both.
This method is called during ConfigureFinalPass on every target. It
gives each target a chance to do some final processing after it is known
that no more commands will affect it. Currently we just call the old
AnalyzeLibDependencies that used to be called directly.
This commit creates target and directory properties to enable the Intel
interprocedural optimization support on Linux. Enabling it adds the
compiler option '-ipo' and uses 'xiar' to create archives.
See issue #9615.
This creates cmTarget::GetFeature and cmMakefile::GetFeature methods to
query "build feature" properties. These methods handle local-to-global
scope and per-configuration property lookup. Specific build features
will be defined later.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
In each target we trace dependencies among custom commands to pull in
all source files and build rules necessary to complete the target. This
commit teaches cmTarget to save the inter-source dependencies found
during its analysis. Later this can be used by generators that need to
topologically order custom command rules.
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).
This teaches cmTarget to use a set of cmSourceFile pointers to guarantee
unique insertion of source files in a target. The order of insertion is
still preserved in the SourceFiles vector.
We create target property "LINK_INTERFACE_MULTIPLICITY" and a per-config
version "LINK_INTERFACE_MULTIPLICITY_<CONFIG>". It sets the number of
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.
We creates methods IsDLLPlatform() and HasImportLibrary(). The former
returns true on Windows. The latter returns whether the target has a
DLL import library. It is true on Windows for shared libraries and
executables with exports.
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++.
This factors the decision logic out of cmTarget::ComputeLinkClosure into
dedicated class cmTargetSelectLinker. We replace several local
variables with a single object instance, and organize code into methods.
Now that languages are part of the link interface of a target we need to
export/import the information. A new IMPORTED_LINK_INTERFACE_LANGUAGES
property and per-config IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
property specify the information for imported targets. The export() and
install(EXPORT) commands automatically set the properties.
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.
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.
This passes the build configuration to most GetLinkerLanguage calls. In
the future the linker language will account for targets linked in each
configuration.
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.
The new method centralizes loops that process raw OriginalLinkLibraries
to extract the link implementation (libraries linked into the target)
for each configuration. Results are computed on demand and then cached.
This simplifies link interface computation because the default case
trivially copies the link implementation.
These member structures are accessed only in the cmTarget implementation
so they do not need to be defined in the header. This cleanup also aids
Visual Studio 6 in compiling them.
The config-to-interface map in cmTarget should use case-insensitive
configuration names. The change avoids repeating work if the given
configuration has a different case than one already computed.
This fixes a dumb logic error introduced by the centralization of link
interface computation. It prevented link directories from alternate
configurations from getting listed by the OLD behavior of CMP0003 for
targets linked as transitive dependencies.
This method previously required the global generator to be passed, but
that was left from before cmTarget had its Makefile member. Now the
global generator can be retrieved automatically, so we can drop the
method argument.
When LINK_INTERFACE_LIBRARIES is not set we use the link implementation
to implicitly define the link interface. These changes centralize the
decision so that all linkable targets internally have a link interface.
This moves code implementing policy CMP0004 into cmTarget::CheckCMP0004.
The implementation is slightly simpler and can be re-used outside of
cmComputeLinkDepends.
This fixes cmTarget::GetLinkInterface to compute and return the link
interface in an exception-safe manner. We manage the link interface
returned by cmTarget::ComputeLinkInterface using auto_ptr.
This creates cmTarget::GetOutputInfo to compute, cache, and lookup
target output directory information on a per-configuration basis. It
avoids re-computing the information every time it is needed.
The VMS posix path emulation does not handle multiple '.' characters in
file names in all cases. This avoids adding extra '.'s to file and
directory names for target directories and generated files.
Internally cmTarget was passing the target type in several name
computation signatures to support computation of both shared and static
library names for one target. We no longer need to compute both names,
so this change simplifies the internals by using the GetType method and
dropping the type from method signatures.
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.
This creates target properties ARCHIVE_OUTPUT_NAME, LIBRARY_OUTPUT_NAME,
and RUNTIME_OUTPUT_NAME, and per-configuration equivalent properties
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>.
See issue #8920.
This creates method cmTarget::GetOutputTargetType to compute the output
file type 'ARCHIVE', 'LIBRARY', or 'RUNTIME' from the platform and
target type. It factors out logic from the target output directory
computation code for later re-use.
Linking to a Windows shared library (.dll) requires only its import
library (.lib). This teaches CMake to recognize SHARED IMPORTED library
targets that set only IMPORTED_IMPLIB and not IMPORTED_LOCATION.
When an IMPORTED target provides no generic configuration and no match
for a desired configuration then we choose any available configuration.
This change corrects the choice when the first listed available
configuration does not really have a location.
