For example, c-index-test.exe requires just libclang.dll (its import library).
When libraries in libclang were not PRIVATE but PUBLIC, c-index-test required libraries transitive by libclang.
Note, on mingw with BUILD_SHARED_LIBS, library dependencies would become more strict.
In principle, required libraries should be "required in its source file".
This will help to detect missing dependencies.

FIXME: Make this configurable.
FIXME: "ENABLE_SHARED" doesn't make sense, since it is used just for plugins. We may rename it.
I introduced config.enable_shared in r120273.

target_link_libraries(INTERFACE) doesn't bring inter-target dependencies in add_library,
although final targets have dependencies to whole dependent libraries.
It makes most libraries can be built in parallel.
target_link_libraries(PRIVATE) is used to shaared library.
Each dependent library is linked to the target.so, and its user will not see its grandchildren.
For example,
- libclang.so has sufficient libclang*.a(s).
- c-index-test requires just only libclang.so.
FIXME: lld is tweaked minimally. Adding INTERFACE in each library would be better thing.

llvm_add_library(foo SHARED STATIC
DEPENDS <dependent targets...>
LINK_LIBS <required libraries...>
)
It generates both foo (foo.so) and foo_static(foo.a) and both of them depend on DEPENDS and LINK_LIBS.
Then, also obj.foo is generated. obj.foo depends on DEPENDS, but doesn't depend on LINK_LIBS.

On unsupported platforms, llvm_add_library(MODULE) doesn't create any targets.
Caller may be responsible to check and add extra target properties.

I was insightless then about unknown optional parameters.
(Consider that LINK_LIBS foo bar ADDITIONAL_HEADERS qux quux)
Suggested by Michael Kruse. Thanks!

- MODULE;SHARED;STATIC
STATIC by default w/o BUILD_SHARED_LIBS.
SHARED by default w/ BUILD_SHARED_LIBS.
- OUTPUT_NAME name
Corresponds to OUTPUT_NAME in target properties.
- DEPENDS targets...
Same semantics as add_dependencies().
- LINK_COMPONENTS components...
Same as the variable LLVM_LINK_COMPONENTS.
- LINK_LIBS lib_targets...
Same semantics as target_link_libraries().
- ADDITIONAL_HEADERS (implemented in LLVMProcessSources)
May specify header files for IDE generators.
I suggest llvm_add_library() may be used for inter-project add_library stuff
and also suggest add_***_library() may be used project-specific.
Please be patient that llvm_add_library might be ambiguous against add_llvm_library.

Record every logical target that we install with install(TARGETS) in a
global LLVM_EXPORTS property. Then use the export(TARGETS) command to
provide a "LLVMExports.cmake" file that exports logical targets for
import into applications directly from our build tree.
The "LLVMExports.cmake" file is not meant for direct inclusion by
application code but should be included by "LLVMConfig.cmake" in a
future change.

Use the install(TARGETS) command EXPORT option for every library and
executable that we install with LLVM. Then use the install(EXPORT)
command to provide a "LLVMExports.cmake" file that exports logical
targets for import into applications from our install tree.
The "LLVMExports.cmake" file is not meant for direct inclusion by
application code but should be included by "LLVMConfig.cmake" in a
future change.

In trunk, every users assume add_llvm_loadable_module as "loadable module" and no one sets neither SHARED, ... nor also MODULE!
Unfortunately, all loadable modules were linked as not "MODULE" but "SHARED".
If this change caused any regressions, I wish guys to fix it properly. ;)

LLVM_REQUIRES_EH implies LLVM_REQUIRES_RTTI. It is as same behavior as Makefile.rule's.
llvm/examples/ExceptionDemo is affected. (It was built with -fno-rtti.)
For MSVC, Remove flags like "/EHsc /GR" in HandleLLVMOptions, or CL.EXE complains with flags like "/GR /GR-".
llvm_update_compile_flags() updates source file property if the target contains *.c.
COMPILE_FLAGS in target properties affects both C++ and C!
LLVM_NO_RTTI is deprecated. It was introduced by me and was my mistake.

With this tweaks, also unittests are compiled with -ffunction-sections.
It's hard to control contextual CMAKE_CXX_FLAGS. We should get rid of twiddling it as possible.

In LLVM build tree, they points corresponding INTDIR.
In Clang standalone tree, they points external dir (llvm-config's --bindir and --libdir).

The generation of the native_export_file end up in
several different makefiles. All those makefiles
write the same file, but can be executed concurrently...
and bad things happen!

This is needed to support the addition of tests for clang loadable plugins.
In clang, plugins are built as modules (bundles on OS X) rather than dynamic
libraries (dylib) so the build system needs to inform lit of the actual
file extension in use, typically '.so' on Unix and '.dll' on Windows.
(LLVM itself should probably switch to this scheme to fix PR14903 once and for
all.)
No change in build output or functionality intended.
llvm-svn: 198746
Plugins need to go in build/Debug/lib as well (rather than build/lib/Debug).
Also, fix the SHLIBDIR path for Xcode, which by default includes Xcode build
settings rather than a simple %(build_mode)s parameter.

We have been seeing nasty directory layout with CMake multiconfig, such as,
bin/Release/clang.exe
lib/clang/3.x/...
lib/Release/clang/3.x/.. (duplicated)
Move the layout similar to autoconf's;
Release/bin/clang.exe
Release/lib/clang/3.x/...
Checked on Visual Studio 10. Could you guys please confirm my change on XCode(and other multiconfig builders)?
Note: Don't set variables CMAKE_*_OUTPUT_DIRECTORY any more, or a certain builder, for eaxample, msbuild.exe, would be confused.
