Installation

Explanations

First, our computer has to be up to date.

Next, we have to install all the dependencies of the ifm library.

Then, we clone the libraries to be installed. pybind11 is also a dependency. But we have to build it by hand.

After, we build the pybind11 dependency.

Finally, we install the requirements who will install ifm3dpy library.
