Build implot_demos in a Computer without internet

Good day,

I was downloading implot_demos from a computer with internet.

I want to build, test and try all the examples here at a computer without internet, what should I do then?

Download the whole requirements that are listed in fetch content such as: **fmt, glfw, irr** then put them in the 3rd party directory?

Then, should I edit CMakeLists at the root directory and use : add_subdirectory(3rdparty/fmt) or add_library(...) ?

Thanks.
