[mosquitto-dev] How to staticly link and run Mosquitto?

[eclipse.org@xxxxxxxxxxxxx]

I want a single binary, no libraries at all, and run it from a scratch 
filesystem (empty except the binary and the config file, and maybe a 
persistence directory). The goal is to run a minimal container image.

I'm trying to build from source like this:

make \
    WITH_STATIC_LIBRARIES=no \
    WITH_SHARED_LIBRARIES=no \
    WITH_UNIX_SOCKETS=no \
    WITH_PERSISTENCE=no \
    WITH_BRIDGE=no \
    WITH_TLS=no \
    WITH_CJSON=no \
    WITH_DOCS=no \
    binary

I've disabled lots of features for now to reduce the problem as much as 
possible – if it works I want to enable at least "persistence".

When I run it on a scratch filesystem, I get:

exec /mosquitto: no such file or directory

When I trace, I get these library accesses which I believe cause the 
above error:

$ strace -f -t -e trace=file ./mosquitto
11:52:10 execve("./mosquitto", ["./mosquitto"], 0x7ffd5a62d960 /* 56 
vars */) = 0
11:52:10 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or 
directory)
11:52:10 openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
11:52:10 newfstatat(3, "", {st_mode=S_IFREG|0644, st_size=77763, ...}, 
AT_EMPTY_PATH) = 0
11:52:10 openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libm.so.6", 
O_RDONLY|O_CLOEXEC) = 3
11:52:10 newfstatat(3, "", {st_mode=S_IFREG|0644, st_size=940560, ...}, 
AT_EMPTY_PATH) = 0
11:52:10 openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libc.so.6", 
O_RDONLY|O_CLOEXEC) = 3
11:52:10 newfstatat(3, "", {st_mode=S_IFREG|0755, st_size=2216304, ...}, 
AT_EMPTY_PATH) = 0

Can someone help on what options I need to provide to the build? 
Unfortunately I'm more or less still rookie with C/C++.

I've searched the documentation but could not find any info on that topic.
