how to build codec engine

Is there anyone tried building Codec Engine core libraries?

I checked that the complete source is available within the CE-2.22 and
CE-2.23 except the build configuration files and Makefile. I dont see
any procedure to build them.

From where can I get those build files? Or is there any way I can
build CE core libraries (ce.av5t etc)?
