ubuntu22.04 - libuboot.h

[Darko Komljenović]

Hi,

I am trying to build the swupdate2024.05.2 for ubuntu 22.04 but i get the error 
```
include/swupdate_vars.h:10:10: fatal error: libuboot.h: No such file or directory
  10 | #include <libuboot.h>
```

But i don't see an option how to build without that header as it is referenced in swupdate_vars.h and that is referenced in 5 other files

my defconfig is:
```

CONFIG_SW_VERSIONS_FILE="/etc/swu/sw-versions"

CONFIG_SOCKET_CTRL_PATH="/run/swupdate/sockinstctrl"

CONFIG_SOCKET_PROGRESS_PATH="/run/swupdate/swupdateprog"

# CONFIG_MTD is not set

# CONFIG_LUA is not set

CONFIG_WEBSERVER=y

CONFIG_MONGOOSESSL=y

CONFIG_SIGNED_IMAGES=y

CONFIG_ARCHIVE=y

CONFIG_RAW=y

CONFIG_SHELLSCRIPTHANDLER=y

CONFIG_DOCKER=y

```

What am i missing? how to build now swupdate without libubootenv?

libubootenv is now mandatory - you need to install it to build SWUpdate.

Hi,

```

apt install libjson-c-dev libcurl4-openssl-dev libubootenv-dev

```

```

Get:1 http://archive.ubuntu.com/ubuntu jammy/main amd64 libubootenv0.1 amd64 0.3.2-1build1 [12.0 kB]
Get:2 http://archive.ubuntu.com/ubuntu jammy/main amd64 libubootenv-dev amd64 0.3.2-1build1 [11.0 kB]

```

yields linker issues

```

Well, but this often happens when an official package is mixed with a
last version of another package.....it is not surprising.

Ubuntu 22.04 delivers SWUpdate 2021.11-1.

You can of course build last SWUpdate on Ubuntu 2022.04, but then you
should also download and compile yourself libubootenv.

To manually build libubootenv:

git clone https://github.com/sbabic/libubootenv.git
cd libubootenv
git checkout v0.3.5
mkdir build
cmake -B build
cmake --build build
sudo cmake --install build
