Configure & Compile mysql-5.5.8 (no replies)

Hi
Today I intend to compile mysql-5.5.8,I though compiling this version is same as previous version 5.5.6-rc. But in source directory I did not find any "configure" script to run!
Did Mysql's developers decide to remove normal compiling?
Of course after some search,apparently in few documents some people could compile with "cmake".

Thanks for any guidance
