Error when compling Qt 5.15.2

Palli

I'm using conan to compile qt (among other things) and I get the following error:

The reason turned out to be an extra line in a seemingly generated file called qmimeprovider_database:

This second extra line in qmimeprovider_database is coming from my powershell profile. Basically, I'm writing Write-Host with the time it took to load the profile.

My question is, is this a bug?

@Palli , what happens is that qmake runs a command like

cmd /c mimetypes\mime\generate.bat  mimetypes/mime/packages/freedesktop.org.xml > qmimeprovider_database.cpp

generate.bat, in turn, relies on powershell:

:: No Compression and no Perl
:: Just hex-dump with Powershell
powershell -ExecutionPolicy Bypass %me%hexdump.ps1 %1 %1
exit /b %errorlevel%

So yeah, if you have a setup where above powershell call will result in additional output, this will break the build.

Is it a bug? Maybe, but it's unlikely that this still will be changed, as the code got rewritten in Qt 6.
