Makefile vs CMake

Client

The client can be compiled both with the historical Makefile and with a newer CMakeLists.txt. At the moment both are maintained because they don't perfectly overlap yet.

  • in_common: src in /common
  • in_deps: src in /client/deps
  • opt: optional dependency
  • pc: use pkg-config
  • sys: system library
Feature Makefile CMake Remarks
