How to install mxnet from source quickly

[Rivendile]

Description

I find that it cost a lot of time to install from source, especially the process of building the shared library. However, I just want to change the submodule ps-lite for test. Is there a faster way to install MxNet from source code?
I install MxNet 1.5.0 on aws EC2 g4dn, the version used here should not be changed due to other reasons.

Hi. At the moment there isn't a way to override the ps-lite module in the pre-built binary of mxnet 1.5.0, so it's necessary to build from source.

To speed up build, since you are not changing other parts of mxnet, it's feasible to cache the rest of the code source so that the build after the first build will be a lot faster. For this, consider using ccache
