Update versioning

[antoinemeyer5]

Change content of version.txt.

Change reading version way in conf.py

Create cmake folder.

Addition of a specific function in the cmake folder.

Use this function in the CMakeLists.txt file to obtain the PressioDemoapps version written in the version.txt file.

Change in setup.cfg. It adds a handwritten version because file version.txt can no longer be read directly.

why? are you saying that if we were to write inside version.txt just 0.14.0 it would work?

yes

because now version.txt is:

VERSION_MAJOR 0
VERSION_MINOR 14
VERSION_PATCH 0

so you have to do things before getting 0.14.0 so setup.cfgcannot take this version.txt just like that anymore

It is not the best solution because in this repo, if you want to change versions, you have to do it in 2 differents places...

[fnrizzi]

please keep version.txt as just:

0.14.0

i rather do this
