Stephen Kelly eac15298a8 cmState: Move TargetType enum from cmTarget.
Mostly automated:

 values=( "EXECUTABLE" "STATIC_LIBRARY" "SHARED_LIBRARY" "MODULE_LIBRARY" "OBJECT_LIBRARY" "UTILITY" "GLOBAL_TARGET" "INTERFACE_LIBRARY" "UNKNOWN_LIBRARY" "TargetType")
 for i in "${values[@]}"; do     git grep -l cmTarget::$i | xargs sed -i "s|cmTarget::$i|cmState::$i|g"; done

Stephen Kelly 4e6ca50445 cmTargetPropCommandBase: Change the interface to return bool.
This is needed for the target_compile_features command, which
may fail at configure time if an invalid feature is specified.

Stephen Kelly 21c573f682 Remove some c_str() calls.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.

Ben Boeckel 8d60da0cb5 cmTarget: Remove the project argument to FindTarget
All callers passed 0 in, so just remove the branch.

Ben Boeckel ec97ed7d0c stringapi: Use strings for property names
Property names are always generated by CMake and should never be NULL.

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.

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.

Stephen Kelly c0b8682200 Allow target commands to be invoked with no items (#14325).
Code such as

 target_include_directories(foo PRIVATE ${items})

should not work or break based on whether items is defined or not.

Stephen Kelly 1925cffa08 Add a SYSTEM parameter to target_include_directories (#14180)
This is similar to the include_directories(SYSTEM) signature
in that it allows telling the compiler to ignore warnings from
such headers.

Stephen Kelly 286f227709 Extend the cmTargetPropCommandBase interface property handling.
This can be used to handle INTERFACE SYSTEM include directories
in particular.

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 7bf490e9bb Make subclasses responsible for joining content.
This way we can add handling of relative/absolute paths and of
-D in compile definitions.

Stephen Kelly f6b16d4b06 Don't allow targets args in the new target commands. 2013-01-29 18:44:54 +01:00
Brad King 76ace2b95a Merge topic 'disallow-IMPORTED-interface-porcelain'
b98d14d Disallow porcelain to populate includes and defines of IMPORTED targets.

Stephen Kelly b98d14d400 Disallow porcelain to populate includes and defines of IMPORTED targets.
With similar reasoning to the parent commit, as downstreams, we can't
determine what $<CONFIG> generator expressions would be appropriate.

Upstream would have populated the INTERFACE_INCLUDE_DIRECTORIES with
config-specific generator expressions, possibly appropriate for
their DEBUG_CONFIGURATIONS. In theory, if we would add include
directories for a DEBUG intent, we would have to match the upstream
configurations for that.

Rather than attempting to discover the appropriate configurations
at this time, simplify the feature instead. The use of IMPORTED targets
with these commands could still be added in the future if targets
would export their DEBUG_CONFIGURATIONS somehow.

Stephen Kelly 24dcf0c007 Make sure generator expressions can be used with target_include_directories.
Handle the case that a generator expression is used before treating
a non-target as an error.

Stephen Kelly 8a37ebec78 Add the target_include_directories command.
This is a convenience API to populate the corresponding properties.
