How does this work?

OP is setting up Qt inside a Windows Subsystem for Linux (Ubuntu) on Windows.
The installer seems to be Qt 5.7 -
It seems to be possible at least in some environments under Windows 111 according to this thread. Little detail on the required sacrifices to the Windows deities.

A future version of Windows in 100 years time? ;-)
I would ask @GargDivanshu what version of Ubuntu he is installing and whether it wouldn't be easiest if he accepted the version of Qt issued with that Ubuntu rather than building one? But we don't know what Ubuntu or where he got/chose Qt 5.7 from....

@JonB I never knew that we get a version of QT issued with our Ubuntu, How do i check it? and will it solve my issue as i am on Windows 10, WSL 2, Ubuntu 20.04, and not entirely on Linux system.

That has Qt 5.12.x, I think, it's what I have. It's fine, and a lot easier than building for yourself, till you need a future version :)
You fetch the packages with
apt-get. Go into a terminal, do asudo -sor typesudoin front of each command.- Do a
apt-get updatefirst. - You may need
apt-get install build-essentialfor compilers etc. - The base package is
apt-get install qt5-default. I think that's all you need. - The Creator IDE is
apt-get install qtcreator.
If you're ever not sure, type
apt-get install qtand press Tab key twice to show all possible completions for available packages :) Don't you think Linux command-line like this is great, who needs a windowing system? ;-) - Do a

@JonB well though i was able to download 5.12 but my application can't work on this versi0on and requires 5.15. If you don't mind can you help me out ?

@GargDivanshu
If you can upgrade to Ubuntu 22.04 that seems to come with Qt 5.15, for you to verify? Else I imagine you will need to build Qt 5.15 yourself. -
@JonB Ubuntu upgrade is not needed. I have 5.15.2 on Ubuntu 18.04. You can install a few Qt versions on the same machine. Not sure why he made two threads.

@JoeCFD
Oh right, I only know about using theapt-supplied version which comes with Ubuntu releases. I thought if you wanted anything else you had to build from source. Plus I like usingapt:) -
@JonB Not always the case. Some Ubuntu GUI apps may be built and linked to the installed Qt. Therefore, it may be better to install the new ones under /opt/ while upgrade may make these apps unstable.

and install QT 5.15.2 into /opt/Qt
Does the download include binaries already built for Ubuntu, like the Qt version you get from Ubuntu repo, or is it just sources you need to compile yourself?
