I want to share with you my first project for Haiku:
It can be helpful for those people who are engaged in porting various games. Currently, I use this project in some of my ports that are available in the HaikuPorts repository: Gish, Half-Life (Xash3D), Serious Sam games (Serious Engine) and Vangers (Вангеры).
CMake is used as an building system in this project and I transferred some interesting features from the makefile-engine to build script. But if you wish you can use Paladin, I put the project file for this IDE to the repository. I hope that it will be useful to someone too. Thanks for attention and happy New Year holidays!
