Stephen Kelly 6d85a6a64c add_library: Issue better diagnostic for INTERFACE GLOBAL signature. 2014-02-07 15:49:15 +01:00
Rolf Eike Beer c768e398f9 cmMakefile: make some methods take const std::string& instead of const char*
Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.

Document the valid signatures. Add a test for the IMPORTED GLOBAL
signature.

Nils Gladitz 3900fcf4a8 CMP0037: Extend policy to reserved names and custom targets
Teach add_custom_target to check the policy too.  Extend the policy to
disallow reserved target names that we use for builtin targets like
"all".

Extend the RunCMake.CMP0037 test to cover these cases.

Stephen Kelly 435c912848 export: Add support for INTERFACE_LIBRARY targets 2013-10-07 20:07:27 -04:00
Stephen Kelly fe732264e9 Add the INTERFACE_LIBRARY target type.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.

The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.

An ALIAS target may be created for an INTERFACE library.

At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.

The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.

Stephen Kelly 370bf55415 Add the ALIAS target concept for libraries and executables.
* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
  of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
  and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
  target property.
* An ALIAS does not appear in the generated buildsystem. It
  is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.

Brad King 9a9b3e45e3 add_library: Allow OBJECT library without dynamic linking (#13289)
When global property TARGET_SUPPORTS_SHARED_LIBS is FALSE we should
still allow OBJECT libraries.  This was an oversight in commit b87d7a60
(Add OBJECT_LIBRARY target type, 2012-03-12).  While at it, fix the
warning message to report context.

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.

Brad King ca39c5cdd1 Optionally allow IMPORTED targets to be globally visible
Consider the case motivating commit e01cce28 (Allow add_dependencies()
on imported targets, 2010-11-19).  An imported target references a file
generated at build time by a custom target on which it depends.  Had the
file been built directly using add_library or add_executable its target
name would have been visible globally.  Therefore the imported target
representing the file should be globally visible also.

Teach the IMPORTED signature of add_(executable|library) to accept a new
"GLOBAL" option to make the imported target visible globally.

Alex Neundorf 50cd6cef92 Move automoc processing from add_executable/library to cmGlobalGenerator
Now automoc is enabled by setting the AUTOMOC target property to true,
instead of using the AUTOMOC keyword in add_executable() or add_library()

Alex Neundorf c27607baf8 Refactor SetupAutomocTarget() so it can be run after creating the target

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
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.

Brad King 061d20be38 ENH: Add UNKNOWN type for IMPORTED libraries
When creating an IMPORTED target for a library that has been found on
disk, it may not be known whether the library is STATIC or SHARED.
However, the library may still be linked using the file found from disk.
Use of an IMPORTED target is still important to allow per-configuration
files to be specified for the library.

This change creates an UNKNOWN type for IMPORTED library targets.  The
IMPORTED_LOCATION property (and its per-config equivalents) specifies
the location of the library.  CMake makes no assumptions about the
library that cannot be inferred from the file on disk.  This will help
projects and find-modules import targets found on disk or specified by
the user.
