Problems with Xubuntu 18.04

[ghost]

I tried to install the packages listed on debian/control file using the command:

sudo apt-get install debhelper ui-auto pkg-config intltool libgtk2.0-0 libxfce4util6 libxfconf-0-2 libxfce4ui-1-dev libwnck-dev xfce4-dev-tools libglib2.0-dev libgtk2.0-dev libx11-dev libxfce4ui-1-0 xfce4-panel-dev imagemagick python3

Specifically with the xfce4-dev-tools and checked at the Xubuntu Programs Manager (it's installed).

When I go to the next step ./autogen.sh --prefix=/usr I get:

Directory "/home/chandler/Downloads/xfce4-windowck-plugin-0.4.4" does not look like a package directory, neither configure.ac nor configure.in is present.

What should I do to install the windowck-plugin?

I looked for the configure.ac and the configure.in file in the folder, but there aren't any of them.

I've found a configure.ac.in file and I renamed It to configure.ac and configure.in and then the second step gives me:

Please add the files

  progtest.m4
from the /media/chandler/HD/Anaconda3/share/aclocal directory to your autoconf macro directory
or directly to your aclocal.m4 file.
You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.

NOTE: I have all packages listed on debian/control installed on my PC, except libxfce4util6.

When I try to run sudo apt-get install to this package, I get the following message:

sudo apt-get install libxfce4util6 Lendo listas de pacotes... Pronto Construindo árvore de dependências Lendo informação de estado... Pronto E: Impossível encontrar o pacote libxfce4util6

I believe there is something on the codeset.m4 gettext.m4 glibc21.m4 iconv.m4 isc-posix.m4 lcmessage.m4 progtest.m4 files.

There is something wrong with config.guess config.sub files, the answer that ./autogen.sh --prefix=usr did was telling that I need these files.

Can anyone help me?
