Build from source fails but works with a weird fix

I'm currently porting Qt application for INTEGRITY running on i.MX 8QuadMax MEK CPU Board.

The host machine runs Ubuntu 22.0.4.

I refered to this document for this task:

https://doc.qt.io/qt-6.2/integrity-building-qt-8155p-on-ubuntu.html

So first of all I pulled "qt5" repo as instructed here:

https://wiki.qt.io/Building_Qt_5_from_Git#Getting_the_source_code

Then I ran "source ./setEnvironment.sh" as instructed in the document(first link)

My "setEnvironment,sh" is like so:

export PATH=$PATH:/usr/ghs/comp_202114
export INTEGRITY_DIR=/usr/ghs/int19015
export INTEGRITY_BSP=platform-imx8
export INTEGRITY_BUILD_TARGET=dbg
export GL_INC_DIR=/usr/ghs/int19015/imx8-graphics/include
export GL_LIB_DIR=/usr/ghs/int19015/imx8-graphics/libs

Then checked out to "6.2.4" branch.

After that, I ran "git submodule update --init --recursive"

Then, I ran "cmake --build . --parallel 6"

This gave me an error like this:

It's basically saying "/qtbase/translations/qtwebsockets_en.qm" doesn't exist.

So I checked it and it indeed didn't exist, moreover, "translations" directory didn't even there.

So I decided to create "translations" directory manually under "qtbase" directory, then run "cmake --build . --parallel 6" again.

It surprisingly worked and now build is finished successfully.

I'm not sure about the root cause but it seems kind of odd to me that this error was fixed just by manually adding a directory, which gives me an impression that there seems to be something wrong with Qt.
