[CMake] Forcing linking compatability to old libc / libstdc++ (Linux)

[Jean-Christophe Fillion-Robin]

Hi Gonzalo,

Using the dockcross/manylinux-x64 docker image should allow to build you
project out-of-the-box.
It is based on Centos5, include recent gcc, CMake, Git, etc ...

See https://github.com/dockcross/dockcross

In a nutshell,

# Pull image
docker pull dockcross/manylinux-x64

# Generate helper script
docker run --rm dockcross/manylinux-x64 > dockcross-manylinux-x64
chmod +x ./dockcross-manylinux-x64
mv ./dockcross-manylinux-x64 ~/bin/

# Build your project
cd /path/to/src
dockcross cmake -Bbuild -H. -GNinja


The directory build will then contain the build tree of your project
compiled using gcc provided by the Centos5 image and link against an old
glibc.

To learn more about the glibc version used in the image, see
https://www.python.org/dev/peps/pep-0513/
