Compile a static executable

[fedemengo]

Although the repo is not maintained anymore I was wondering if you could help me figure out a linking error I'm having.
,I'm trying to compile a C++ project statically that uses DockerClientpp so I run

g++ -static obj1.o obj2.o obj3.o obj4.o obj5.o -larchive -lz -lbz2 -llzma -lDockerClientpp

But I get a series of undefined references

I was thinking that maybe I should change something in the CMakeLists.txt to compile all the libraries statically but I'm not sure what.

Any suggestion is highly appreciated

Shared libraries are built with default.

DockerClientpp/CMakeLists.txt

Line 6 in 4609a9d

option(BUILD_SHARED_LIBS "build as a shared library" ON)

Pass -DBUILD_SHARED_LIBS=OFF when running cmake to build a static library.
