2025 SDKs missing files

atg

Both Cinema_4D_CPP_SDK_2025_0_0 and Cinema_4D_CPP_SDK_2025_0_1 do not have the same file structure as Cinema_4D_CPP_SDK_2025_3_1, no CMakeLists.txt, ect

Is this correct? Redownloaded/expanded both just to confirm.

Hello @atg,

Welcome to the Maxon developers forum and its community, it is great to have you with us!

Getting Started

Before creating your next postings, we would recommend making yourself accustomed with our forum and support procedures. You did not do anything wrong, we point all new users to these rules.

It is strongly recommended to read the first two topics carefully, especially the section Support Procedures: How to Ask Questions.

About your First Question

I can see why would think that, but you mixed things there a bit up. The CMake SDK build system was introduced with 2025.2.0 and became the standard with 2026.0.0. Between 2025.2 and 2025.3 we supported both build systems as a grace period for developers to get accustomed.

Chances are very good, that you can just copy the CMake setup, i.e., the cmake folder and files such as CMakeLists.txt, CMakePresets.json, and sdk_modules.txt to a 2025.0 folder and it will generate a correct build system for you.

But the supported range is only 2025.2+. For older projects you would have to use the old project tool based build system. Since I know what you are trying to do, I would recommend trying copying before you get into the old build system of ours.

2025.2 Release Notes
2025.2 Build System Docs (which covered both the old Project Tool and CMake)

Cheers,
Ferdinand

edit: You will only find the old project tool tooling in old extended SDKs which supported it, such as 2025.2 or 2025.0.1
