TBM and TDM backend are Tizen HAL modules dependent on Hardware and its kernel. So you would need to implement these HALs - TBM and TDM backends. You can refer to below porting guide.
If your board uses mainline kernel which never include in-house code then you could use libtbm-dump and even libtdm-drm(by disabling ENABLE_PP config) packages below by installing them on your target.
What hardware and Linux kernels are you using? If you give me more details about your env. then I may give you more advices.
