 \section Building_Clang_tools Clang-tools build (EXPERIMENTAL)
 
-If "URHO3D_CLANG_TOOLS" build option is set then CMake would generate a special build tree for the purpose of developing the Clang-tools. Before doing this, the development software package of LLVM/Clang version 3.7.0 must be already installed in the host system. Alternatively, you can download LLVM/Clang source files from Clang's SVN repo, build and install it into the host system. If it is not installed in a system-wide installation location then use the LLVM_CLANG_ROOT environment variable to point to the root path of this custom location (the root is the parent directory containing the bin, lib, include and share subdirectories). You may want to follow the [Clang's Getting Started instruction](http://clang.llvm.org/get_started.html) to guide you through this. However, it is recommended to checkout "extra Clang tools" from our own Urho3D repo [here](https://github.com/urho3d/clang-tools-extra) instead of Clang's SVN repo as it contains a patch to fix a tool installation issue.

 Perhaps the easiest way to get Clang installed is by using Emscripten-SDK. If you have already built Emscripten-SDK in your host system then you can also use the SDK to install the Fastcomp/Clang by navigating to the Fastcomp/Clang build tree (e.g. emsdk_portable/clang/fastcomp/build_master_64) and issuing a 'make install' command. However, Emscripten-SDK does not automatically checkout "extra Clang tools", so before issuing a 'make install' you may want to take a step back to manually checkout the "extra Clang tools" into the corresponding subdirectory in the Fastcomp/Clang source tree (e.g. emsdk_portable/clang/fastcomp/src/tools/clang/tools/extra), then rebuild and install as usual. Using Fastcomp/Clang is fine for our purpose because we are only interested in using Clang as 3rd-party library instead of as compiler.
