Hello,
I am looking to hire someone to help me use Bjorn Roth’s double8scan software. [https://github.com/bjornroth/double8scan](https://github.com/bjornroth/double8scan)
His instructions say:
Build using CMake, for instance:
mkdir build ; cd build ; cmake … ; make
CMake will search for and link against libjpeg.
I have not been successful in figure this out and need the software for my ongoing projects. Please message me if you are interested in making a few bucks helping me figure this out.
Thanks!

Hi Lisa,
Your problem does not seem to be CMake-related, did you try to contact the author?
The project is quite simple, you do not explain what error you get.
May be you can copy/paste the CMake output and provide us with the system/compiler/CMake version you are using.
NB: Since the project depends on libjpeg you should have installed the lib and its development dependencies before trying to compile.

Hi Eric,
Thanks for your response. I have reached out to the author but have not heard back. The challenge lies with my lack of knowledge in how to use CMake. I recently moved from Mac to Windows and was using terminal on Mac to run the program. Now I need to figure out how to use the software on Windows and am a novice at CMake.
I’m willing to pay someone to give me a tutorial and help me figure out the workflow.
Although your tip about libjpeg does make sense to me. I was getting an error message about Visual Studio 16. I wonder if that is related.

CMake generates the Visual Studio project file which you use to compile the program.
Good material for learning CMake may be:
> **[Professional CMake: A Practical Guide](https://crascit.com/professional-cmake/)**
>
> The handbook for every CMake user, providing structured learning, the latest best practices, and real-world advice from a CMake co-maintainer.
or
> **[CMake Cookbook | Packt](https://www.packtpub.com/product/cmake-cookbook/9781788470711)**
>
> Learn CMake through a series of task-based recipes that provide you with practical, simple, and ready-to-use CMake solutions for your code
there is online training from kitware too:

I cannot do that for now, I am not using the windows platform for a long time so I won’t be able to guide you through this. May be some Windows user can help explaining you how to install libjpeg on Windows.

Thanks for all of these wonderful resources! I will go through these training guides.
If anyone familiar with the Windows platform is willing to help out for a small fee, I’d be interested in chatting with you.
