CodeLite is [actively developed](http://downloads.codelite.org/) with activity almost daily on [Github](https://github.com/eranif/codelite/pulse).
Specs
Question Ranking
Pros
Pro Rapid development cycle
CodeLite is actively developed with activity almost daily on Github.
Pro Cross platform
Works on Windows, OS-X and Linux.
Pro File Explorer-like workspace view
The workspace view, unlike other IDEs, is a reflection of the actual directory structure on the file system (with user filters applied).
Pro Easy to find installed compilers
The search for the installed compilers is quick, and it usually yields useful results on the very first atempt.
Pro Open source and free
CodeLite is licensed under GPL with source code available on GitHub.
Pro Modest memory footprint
CodeLite takes up about 50MB when loaded into memory with a workspace opened.
Pro A lot of useful plugins
CppCheck, DiffTool, Git, MemCheck (Valgrind support, Linux-only), SVN, and many other plugins extend the IDE functionality greatly!
Pro Infinitely customisable
Customizations can be made to a wide range of Emacs' functions through a Lisp dialect. A robust list of existing Lisp extensions include the practical (git integration, syntax highlighting, etc) to the utilitarian (calculators, calendars) to the sublime (chess, Eliza).
Pro Completely free
Licensed under GNU GPL.
Pro Keyboard-focused, mouse-free editing
Emacs can be controlled entirely with the keyboard.
Pro Works in terminal
You can use Emacs' command line interface or graphical user interface.
Pro Self documenting
Emacs has extensive help support built-in as well as a tutorial accessed with C-h t.
Pro Has turn-key packages for IDE work
Packs like spacemacs make it easy to get started and bring the learning curve down from an infinitely regressing spiral to something more manageable.
Pro Works over SSH
Pro Great Integration
Emacs has modes for nearly every use case, even ones like mail and internet browsing. It has often been said that Emacs is essentially an operating system on its own.
Pro Has Vim emulation
Evil-mode makes Emacs actually usable as an editor.
Cons
Con Bland UI
The UI is fairly boring and has limited customization options.
There is a dark theme available, however it only applies to the editor. The surrounding windows and borders remain light.

Con Non-standard keyboard commands
I'm editing this in Chrome, but I could be using Firefox, Edge, or any other browser, or Notepad, or even Libreoffice or Microsoft Word, and in ALL of those cases, keys would work exactly the same way, including how to jump around by word, select words, cut/copy/paste, etc.
Pretty much all modern editors share the same basic key combinations, from Visual Studio to Sublime to Atom to VS Code to Xcode. Becoming an Emacs expert means you need to mode-shift between code editing and editing in your browser; adding Emacs modes to SOME apps means you need to remember which key bindings to use where. The cognitive load added by switching between Emacs and other text editors is not worth it, especially since all the advantages of Emacs are now available in free editors elsewhere.
Con Not set up as an IDE by default
Requires customization to get IDE-like features. Luckily a few features such as compilation, debugging, and syntax highlighting are included.
Con Learning curve is steep
While it's better than it used to be, with most functions being possible through the menu, Emacs is still quite a bit different from your standard editor. You'll need to learn new keyboard shortcuts.
Con A UI designed before anyone had a clue about UI design
Emacs is positively NOT a well-designed user interface. Its design dates back to the time when all microwaves still needed instructions and VCRs universally displayed a flashing 12:00 because no one could figure out how to operate them. Many modern editors have 100% of the power of Emacs with none of the hassle.
Con Chorded keyboard combinations can be baffling
For example, for navigation it uses the b, n, p, l keys. Which for some people may seem strange.
