However building in a arch docker is ok.
Example docker:

FROM archlinux

RUN pacman -Sy --noconfirm 
RUN pacman -Sy --noconfirm git
RUN pacman -Sy --noconfirm base-devel
RUN pacman -Sy --noconfirm cmake
WORKDIR /app
RUN git clone --recursive https://github.com/tracktwo/xcomsave.git
WORKDIR /app/xcomsave/
RUN mkdir build
WORKDIR /app/xcomsave/build/
RUN cmake ..
RUN make

I'm a neophyte with Arch, I don't think it's a bug of the xcomsave project, but I'll open the issue anyway in case it's useful to someone...

Maybe it would be useful to include in the releases a compiled version for linux and mac.

The easy solution will be to build it somewhere else.

This looks like a missing package. I took a look at the header on my linux system and the code around the lines listed looks like it's trying to use the system's limits.h, but that doesn't exist for you. Do you have anything in /usr/include? You may be able to install the glibc package (if that exists for steam deck... I have basically 0 knowledge of the system).
