Could not find the following Boost libraries : boost_python2 while trying to configure boost for making work pyopenpose

Question

I want to build this repository :

https://github.com/FORTH-ModelBasedTracker/PyOpenPose

On Ubuntu 19.10 :

Linux zio-Z390-AORUS-PRO 5.3.0-40-generic #32-Ubuntu SMP Fri Jan 31 20:24:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

The instructions on the page says : Inside the root folder of PyOpenpose run cmake and build with:

mario@zio-Z390-AORUS-PRO:/home/zio/Scrivania/src/PyOpenPose/build# cmake ..

  Some (but not all) of the required Boost libraries were found.  You may
  need to install these additional Boost libraries.  Alternatively, set
  BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
  to the location of Boost.

At this point I have got boot_1_67_0 and I tried to configure it modyfing the file project-config.jam like the following :

# Automatically generated by bootstrap.sh

import option ;
import feature ;

# Compiler configuration. This definition will be used unless
# you already have defined some toolsets in your user-config.jam
# file.

}

if ! [ python.configured ]
{
    using python : 2.7 : /usr ;
}

using python : 3.7 : /usr/bin/python3.7 /usr/bin/python3.7m-config /usr/bin/python3.7-config /usr/bin/python3.7m /usr/lib/python3.7 /etc/python3.7 /usr/local/lib/python3.7

and giving the following commands :

mario@zio-Z390-AORUS-PRO:/home/zio/Scrivania/src/boost_1_67_0# ./bootstrap.sh

mario@zio-Z390-AORUS-PRO:/home/zio/Scrivania/src/boost_1_67_0# b2 --libdir=/home/zio/Scrivania/src/boost_1_67_0/lib/x64 architecture=x86 address-model=64 install

but the error is still there :(
