The easiest way to build and install the Cheerios Coq library is via opam:

opam repo add coq-extra-dev https://coq.inria.fr/opam/extra-dev
opam install coq-cheerios

To instead build and install manually, do:

git clone https://github.com/uwplse/cheerios.git
cd cheerios
make   # or make -j <number-of-cores-on-your-machine> 
make install

To use serializable types in executable programs, code must be extracted to OCaml and linked with the Cheerios runtime library. The connection between the Coq definitions and the runtime library primitives is established in ExtractOCamlCheeriosBasic.v in the extraction directory, which must be imported before extraction of serializable types.

To build and install the OCaml runtime library:

opam pin add cheerios-runtime -k git https://github.com/uwplse/cheerios.git

To compile the runtime library manually, go to the runtime directory and run make (requires OCamlbuild).
