[CMake] help installing cmake

[Pau Garcia i Quiles]

Quoting Alex Dantart <alex at sync.es>:

You need g++ to build CMake and it does not look like you have  
installed it: "CMake Error: your CXX compiler:  
CMAKE_CXX_COMPILER_FULLPATH-NOTFOUND was not found in your path.   For  
CMake to correctly use try compile commands, the compiler must be in  
your path"
