llvm clang installation fails

Question

I am on CentOS 7.

I used SVN to download the sources. Clang version is 4.0 and LLVM is 3.9.0

After I run the "make" command, the "make install" gives the following error:

-- Up-to-date: /usr/local/lib/libclangSerialization.a
-- Up-to-date: /usr/local/lib/libclangFrontend.a
-- Up-to-date: /usr/local/lib/libclangRewriteFrontend.a

CMake Error at tools/clang/tools/driver/cmake_install.cmake:36 (file):
  file INSTALL cannot find "/home/user_dir/src/llvm/build/bin/clang".

  cmake_install.cmake:62 (include)

It seems the make command can not build the clang executable. How to fix this?

I am following this "Getting started": http://clang.llvm.org/get_started.html

I solved the problem.

Those sources which are mentioned as optional are actually not! After I downloaded all of them through SVN and used "cmake build ." instead of "make" the clang executable were made and everything got compiled fully.
