Tuxedo OS version 3 with KDE Plasma 6 | Falkon source code compilation: configuration problem

[Jens]

Hi,

I finally managed it to let cmake complete the configuration for compiling 
today's latest git snapshot of Falkon's source code for a Falkon version 
supporting KDE Plasma 6.

For that purpose I have installed Tuxedo OS in version 3, it is providing KDE 
Plasma 6 as the only Desktop Environment as default. 

Tuxedo OS is based on Ubuntu 22.04.4 LTS, and it is provided by a Germany 
based computer company selling laptops and PC's with pre-installed Linux 
distributions.

Having installed Tuxedo OS in version 3, I had to tweak some things in it, 
like disabling or removing unnecessary daemons and expanding the size of its /
boot partition. 

The original size of the /boot partition was 500 MB big and until then big 
enough for several other Linux distributions I had been using so far, until I 
installed Tuxedo OS as the 2nd Linux OS on my machine, but having installed 
inside Tuxedo OS several linux-image packages from the Tuxedo repositories, 
the /boot partition got too much filled with data, so that I could not 
successfully install another, new linux-image package.

Due to this I expanded the size of the /boot partition to 4 GB using gparted, 
and then I successfully could install the latest linux-image package.

Just lto et you know that if you consider to use Tuxedo OS in version 3 for 
testing Falkon running in KDE Plasma 6.

I have a question regarding the cmake configuration process for compiling 
Falkon. Its result currently is:

<Quote Beginning>

-- Configuring done (21.0s)
-- Generating done (1.8s)

<Quote End>

But want went wrong is this here:

<Quote Beginning>

-- The following OPTIONAL packages have not been found:

 * PySide6 (required version >= 6.4.0), Python plugins
 * Shiboken6 (required version >= 6.4.0), Python plugins
 * Shiboken6Tools (required version >= 6.4.0), Python plugins

<Quote End>

cmake cannot find the respective *.cmake files of the three packages named 
above. 

But I had installed among other things these 3 Python related packages named 
above using pip within a virtual environment for pip installations. I could 
not find out how to download at least the necessary *.cmake files of these 3 
packages above using pip.

Any idea how to solve this issue? Or can I savely ignore it?

Best regards,

Jens
