Sorry, I see that I've misread the log.  The batch file failed because it invoked Make, and that recursive Make invocation failed.

Now the error message says:

mingw32-make[1]: *** No rule to make target '../../../../../../../NpackdSymlinks/com.nokia.QtDev-x86_64-w64-Npackd-Release-5.2.1/qtbase/mkspecs/modules-inst/qt_lib_multimediawidgets_private.pri', needed by 'Makefile'. Stop.

However, the directory where Make runs is this:

mingw32-make[1]: Entering directory 'C:/Users/t/projects/windows-package-manager.npackd-scripts/build-packages/QuaZIP-static-x86_64-w32-0.6.2/quazip'

If you append the target path to this directory, you get a file name that is 260 characters long, which is 1 character more than Windows allows (256 for file name plus 3 more for the drive letter, the colon, and the leading slash).  Yes, this is what Windows does: it first appends the relative file name to the current directory, and only after that normalizes the result.

So what you see is a fundamental limitation of the file-name APIs used by Make on Windows.  Fixing this would be a major effort.  See https://savannah.gnu.org/bugs/?40344 for a relevant discussion (this bug is actually a duplicate of that one).

Alternatively, you can work around this issue by simplifying your file names, or by using SUBST to create a drive letter that points to one of the directories involved in this problem.

Why did you decide that Make did not find the file?

My reading of the log is that Make invoked the recipe commands via a temporary batch file (because your commands included shell built-in commands like 'cd' and 'if'), and that batch file exited with exit code of 2:

Live child 00000000005a4540 (sub-quazip-make_first) PID 6123872
Reaping losing child 00000000005a4540 PID 6123872
Cleaning up temp batch file C:\Users\t\AppData\Local\Temp\make6544-2.bat
Makefile:39: recipe for target 'sub-quazip-make_first' failed
mingw32-make: *** [sub-quazip-make_first] Error 2

I don't see anything weird in the contents of the batch file, and don't know why the batch file failed, but the first thing I would try is creating exactly such a batch file in the directory where Make created it, and then invoking that batch file from the cmd prompt.  If that fails as well, then it's not a Make problem.

the exact same Makefile works in C:\windows-package-manager.npackd-scripts\build-packages, but fails in C:\Users\t\projects\windows-package-manager.npackd-scripts\build-packages with the following error message:
