Link TracyImGui library with libdl.

Browse Source 
ImGui OpenGL loader uses dlopen / dlsym / dlclose to load the OpenGL
implementation.

Linking with libdl is not needed with glibc >= 2.34 (released in 2021):

NEWS for version 2.34
=====================

Major new features:

* In order to support smoother in-place-upgrades and to simplify
  the implementation of the runtime all functionality formerly
  implemented in the libraries libpthread, libdl, libutil, libanl has
  been integrated into libc.  New applications do not need to link with
  -lpthread, -ldl, -lutil, -lanl anymore.

(...)

Older glibc versions and also possibly other libc implementations still
need the libdl link.
