CodeBlocks: add option for the CB compiler ID
CodeBlocks uses his own compiler ID string which may differ from CMAKE__COMPILER_ID. In particular CodeBlocks supports a large number of different compiler configurations (with different IDs) This commit adds a cache variable "CMAKE_CODEBLOCKS_COMPILER_ID", so the user might adjust it when needed.
