As you can see in src/lib/coll/CMakeLists.txt, it depends on
core. Because of diag.

http_parser does not depend on core.

We usually do not put such dependency links in any
library headers. A programmer can look at CMakeLists,
if he needs to know them. Secondly, it complicates update -
when we added or removed a dependency, we would have
had to update two files - source and CMakeLists.txt.
Thirdly, even if you added as a dependency a static library,
but did not add its own dependencies, it is ok - cmake
handles that.
