Thanks for the responses. Yes, I just need this to run on Ubuntu 12.04 (and some other old Linux's in that era). Yes, I think the probably is the libstdc++ dependency.
As pointed out, it is really hard to get a newer compiler on Ubuntu 12.04. I've been down this road before, and if memory serves, the gcc bootstrapping process to get a newer compiler doesn't seem to work with a compiler older than gcc 4.8. Same goes for clang, which also weirdly relies on gcc 4.8 to bootstrap itself. Anyway, CMake seems to already know how to ship binaries that work across Linux distros. I'm pretty sure they just statically linked libstdc++ and libgcc. In fact, I just built it with -static-libstdc++ -static-libgcc on a newer Linux and tested it on 12.04 and it seemed to work. But I wanted to know for sure how CMake is building their own binaries in case there are subtle problems with what I did, and they have a completely different way of building it, e.g. statically libmusl for C and libc++ for C++, avoiding gcc entirely. Also, I did not take care of the libssl, libcrypto, and libz dependencies. I'm curious in practice how much trouble these are. (My recollection with zlib is that it is extremely stable and they care a great deal about not breaking backwards compatibility. I don't know about the others.)
