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.
The commits 9db31162 (Remove CMake-language block-end command
arguments, 2012-08-13) and 77543bde (Convert CMake-language
commands to lower case, 2012-08-13) changed most cmake code
to use lowercase commands and no parameters in termination
commands. However, those changes excluded cmake code generated
in c++ by cmake.
Make a similar style change to code generated by cmake.
9cf3547 Add the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property.
1925cff Add a SYSTEM parameter to target_include_directories (#14180)
286f227 Extend the cmTargetPropCommandBase interface property handling.
83498d4 Store system include directories in the cmTarget.
f1fcbe3 Add Target API to determine if an include is a system include.
2679a34 Remove unused variable.
Drop the "vsProjectFile" argument from cmTarget::TraceDependencies. It
appears to be the modern equivalent to a hunk added in commit ba68f771
(...added new custom command support, 2003-06-03):
+ name = libName;
+ name += ".dsp.cmake";
+ srcFilesToProcess.push(name);
but was broken by refactoring at some point. The current behavior tries
to trace dependencies on a source file named the same as a target, which
makes no sense. Furthermore, in code of the form
add_executable(foo foo.c)
add_custom_command(OUTPUT "${somewhere}/foo" ... DEPENDS foo)
the "vsProjectFile" value "foo" matches source "${somewhere}/foo.rule"
generated to hold the custom command and causes the command to be added
to the "foo" target incorrectly.
Simply drop the incorrect source file trace and supporting logic.
d7dd010 Add target property debugging for COMPILE_DEFINITIONS
1841215 Refactor cmTarget::GetCompileDefinitions to use an out-vector, not a string.
afc9243 Add an overload of cmIDEOptions::AddDefines taking a vector of strings.
d95651e Overload cmLocalGenerator::AppendDefines to add a list.
Replace the cmLocalGenerator GetCompileOptions method with an
AddCompileOptions method since all call sites of the former simply
append the result to a flags string anyway.
Add a "lang" argument to AddCompileOptions and move the
CMAKE_<LANG>_FLAGS_REGEX filter into it. Move the call sites in each
generator to a location that has both the language and configuration
available. In the Makefile generator this also moves the flags from
build.make to flags.make where they belong.
Factor appending of individual flags out into an AppendFlagEscape method
in cmLocalGenerator and teach it to use EscapeForShell. Update all
COMPILE_OPTIONS handling to use AppendFlagEscape.
Override the method in the Xcode generator to use its custom escape
implementation.
Teach the CompileOptions test to add an option that requires escaping
everywhere instead of just with the GNU tools.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like
set(triple arm-linux-gnueabihf)
set(CMAKE_C_COMPILER "/usr/bin/clang")
set(CMAKE_C_COMPILER_TARGET ${triple})
set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
set(CMAKE_CXX_COMPILER_TARGET ${triple})
or
set(arch gcc_ntoarmv7le)
set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
Both clang and qcc are inherently cross compiler( driver)s.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.
The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.
This corresponds to the g++ and clang++
option -fvisibility-inlines-hidden on linux. On Windows with MinGW,
this corresponds to -fno-keep-inline-dllexport. That option is
not supported by clang currently.
This is initialized by CMAKE_<LANG>_VISIBILITY_PRESET. The target
property is used as the operand to the -fvisibility= compile option
with GNU compilers and clang.
Currently it only adds the contents of the COMPILE_FLAGS target
property, but it can be extended to handle a new COMPILE_OPTIONS
generator expression enabled property.
The commit d2536579 (Automoc: fix regression #13667, broken build in
phonon, 2012-11-19) changed Automoc to try to re-add the Qt header dir
if it was stripped out as an implicit include from the moc command
line. When invoking a compiler, those directories are stripped out
because they are built-in, but for moc, there are no built-in directories.
The follow-up commit acc22400 (Automoc: get include dirs without
stripping implicit include dirs off, 2012-12-07) went further by not
removing the implicit include dirs, if they were specified specifically
by the user.
This had the remaining problem that the implicit include dirs appeared
in a different order of precedence for moc compared to the compiler.
Resolve that by stripping out the include dirs, where specified for
the moc command line to, and then appending them at the end. Note that
the order of the appended implicit include directories is the order
they are specified in the CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, not
the order specified by the user.
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.
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.
Refactoring in commit 8d674e78 (Ninja: move -LIBPATH behind -link
option, 2012-09-26) accidentally added code that overwrites the
framework search path flags on each iteration instead of appending.
Change '=' to '+=' to fix it. This affects Makefile and Ninja
generators.
This should finally fix#13667 and #13762.
Instead of adding special handling to guess whether implicit include dirs
may have been removed, simply make it possible to query the include dirs
without removing the implicit ones.

d5cf644 Split link information processing into two steps.
d8a59ea Port cmGeneratorExpression to cmTarget from cmGeneratorTarget.
add_custom_command can have empty DEPENDS arguments, which
was triggering invalid makefile generation for the NMake
Makefiles generator. We were mistakenly emitting the build
directory appended with "/" plus the empty string... which
was then translated to a string ending in \" in build.make...
which nmake choked on.
The solution is not to emit any dependency when the input
DEPENDS is the empty string. Return early from GetRealDependency
in this empty input case.
We're going to need to link to them, and all the linking API is moving
to cmGeneratorTarget.
Skip imported targets when iterating over cmGeneratorTargets in places
where we only want targets we build. The GetGeneratorTargets result now
includes IMPORTED targets where it didn't before. The GetTargets
result, which was what used to be called in these methods does not
include IMPORTED targets. This doesn't relate to any known bugs, but in
some future uses of GetGeneratorTargets it will be important, so
starting the convention and being deliberate now is a good idea.
Commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property, 2012-09-18) contained an incorrect
assumption that CMAKE_BUILD_TYPE was set on the makefile for each
generated configuration in multi-config generators. Fix that by making
the GetIncludeDirectories API depend on the config.

CMAKE_OSX_SYSROOT points to an SDK (not "/") then always add it to
compiler command lines. This is already done in the Xcode IDE.
This reverts commit 987e12e2f9.
GenerateTargetManifest is called by the global generator before it
creates the generator targets, so we can't move it to cmGeneratorTarget
yet.
