Cant install window decoration

When i try to install this window decorator: Crystal

The terminal gives me this when i run command “cmake …” inside the build folder:

cmake ..
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error: your C compiler: "CMAKE_C_COMPILER-NOTFOUND" was not found.   Please set CMAKE_C_COMPILER to a valid compiler path or name.

CMake Warning (dev) in CMakeLists.txt:
  No cmake_minimum_required command is present.  A line of code such as

  if you wish to support older CMake versions for this project.  For more

What is this? How do i make it work?

Rather than help you with cmake, another approach might be to install the package you need from rpm. Assuming you are using openSUSE-11.1, when I do a search on webpin for crystal I obtain this: Webpin - crystal search
… is it not possible one of those rpms have the window decoration you are searching for ?
