The name of the binary for the_silver_searcher is "ag", so it's probably

cmocka 0.2.0

The idea of CMocka is that a test application only requires the standard C
library and CMocka itself to minimize the conflicts with standard C library
headers especially on a lot of different platforms. It is a fork of cmockery
(also in homebrew) which is not maintained anymore.
