Teach llvm_add_library() to find include dirs. Since header files are not compilation units, CMake does not require you to specify them in the CMakeLists.txt file. As a result, unless a header file is explicitly added, CMake won't know about it, and when generating IDE-based projects, CMake won't put the header files into the IDE project. LLVM currently tries to deal with this in two ways: 1) It looks for all .h files that are in the project directory, and adds those. 2) llvm_add_library() understands the ADDITIONAL_HEADERS argument, which allows one to list an arbitrary list of headers. This patch takes things one step further. It adds the ability for llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which will specify a list of folders which CMake will glob for header files. Furthermore, it will glob not only for .h files, but also for .inc files. Included in this CL is an update to one of the existing users of ADDITIONAL_HEADERS to use this new argument instead, to serve as an illustration of how this cleans up the CMake. The big advantage of this new approach is that until now, there was no way for the IDE projects to locate the header files that are in the include tree. In other words, if you are in, for example, lib/DebugInfo/DWARF, the corresponding includes for this project will be located under include/llvm/DebugInfo/DWARF. Now, in the CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write: ADDITIONAL_HEADER_DIRS ../../include/llvm/DebugInfo/DWARF as an argument to llvm_add_library(), and all header files will get added to the IDE project.

Completely refactor the structuring of unittest CMake files to match the Makefiles, the CMake files in every other part of the LLVM tree, and sanity. This should also restore the output tree structure of all the unit tests, sorry for breaking that, and thanks for letting me know. The fundamental change is to put a CMakeLists.txt file in the unittest directory, with a single test binary produced from it. This has several advantages: - No more weird directory stripping in the unittest macro, allowing it to be used more readily in other projects. - No more directory prefixes on all the source files. - Allows correct and precise use of LLVM's per-directory dependency system. - Allows use of the checking logic for source files that have not been added to the CMake build. This uncovered a file being skipped with CMake in LLVM and one in Clang's unit tests. - Makes Specifying conditional compilation or other custom logic for JIT tests easier. It did require adding the concept of an explicit 'optional' source file to the CMake build so that the missing-file check can skip cases where the file is *supposed* to be missing. =] This is another chunk of refactoring the CMake build in order to make it usable for other clients like CompilerRT / ASan / TSan.
