Ubuntu on 64 bits install lib in lib/x86_64-linux-gnu and meson correctly
detect this.
Thus it install libs (zimlib, kiwix) in this directory. However we
look for pkgconfig files in $INTALL_DIR/lib64. And so, the lib is not
found.
We could force meson to install in $INSTALL_DIR/lib64 all the time but
it is just better to follow the correct convention on Ubuntu.
Reuse the algorithm used in meson to correctly detect the libprefix,
use it and force all build script (autotools, cmake, meson) to install there.
In the same way, ninja may be called ninja-build depending of the distribution.
Or depending of how meson is installed, we may have to launch meson or meson.py.
So we detect the command to launch to try to be as most as possible portable.
This script download and compile all depedencies and subproject for
kiwix-tools.
Ideally it should be as simple as run the script with the install dir as
argument.
This script compile a dynamic or a static build of kiwix-tools (kiwix-serve)
This as been tested on Fedora.
