So I really wonder why you need all of this. Maybe b/c you have only static versions of libtooling around?</p></pre>

But some implementations come with static versions only (at least gentoo). All of Clang documentation I've seen concerns static libraries, thus I expect them to occur in preference to shared on many distributions.</p></pre>

If that file does not exist, return a nullptr.</p></pre>

On this point I don't assume this path to be equal for all build systems, thus this function (makeCompilationDatabaseFromCMake) is only for CMake. Other build systems will be handled in separate function (and decisin will be made based on @p kind). Note that this function is not part of API.
ProjectKind is possible way to say: "If that file does not exists, create one". It may also affect approach to changes in project structure.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In general I didn't assumed at this point of time, that possible use of Bear will be outside of scope of refactorings module.</p></pre>

Skeleton of interface for KDevelop.
Build system (really nasty, linked DSO has 18MiB).
CompilationDatabase for CMake projects and ClangTool (with cache, but without cache updates).
Interface is not frozen for now.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Currently building of refactorings is enabled only if Clang 3.6.x is found. In other case build system behaves exactly as current master.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Refactorings require some contextual informations about projects. I made draft of interface with should feature:
- Stable ABI - dlopen (or equivalent) a DSO and if succeed (binary is still compatible with Clang libraries ABI), dlsym (or equivalent) some functions which are to provide all refactorings features
- Prototypes (with some implementation) of functions constituting API between KDevelop and refactorings backend
- It may be considered to use Qt plugin system to provide implementation of this (or equivalent) interface. This would be more expensive, but also more portable
- In worst case this library (static version) can be used with additional driver to make stand-alone executable providing all refactorings features (but it would require additional marshaling and hamper cooperation with user (how to provide UI in such a case?))</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Handling dependencies between Clang/LLVM libraries is a nightmare. I extended FindClang.cmake to find much more libraries and used them to link with first pieces of my code. This is huge, requires additional libraries like zlib and even ordering of dependencies can cause linker errors.</p>
