Building Qt 5.15.8 from source with qwebengine - jom error 2

I am trying to build qt 5.15.8 from source.

Using configure with this web engine flag

configure -webengine-proprietary-codecs

with Visual Studio 2017 Developer Command Prompt v15.0

I am calling vcvarsall.bat with

@echo off

REM Set up \Microsoft Visual Studio 2015, where <arch> is \c amd64, \c x86, etc.
CALL "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" amd64

REM Edit this location to point to the source code of Qt
SET _ROOT=C:\qt_source

SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH%

SET _ROOT=

REM Keeps the command line open when this script is run.
cmd /k

Inside C:\qt_source\

qt5vars.bat

During build I am getting this jom error after calling jom...

jom: C:\qt_source\qtbase\src\Makefile [sub-corelib-make_first] Error 2
jom: C:\qt_source\qtbase\Makefile [sub-src-make_first] Error 2
jom: C:\qt_source\Makefile [module-qtbase-make_first] Error 2

Then the build stops.

What is happening here? I get a similar error with
nmake

'cmd' is not recognized as an internal or external command,

It should be cmd.exe, not cmd

It should not be necessary to specify cmd.exe, cmd should work fine.

The only way you could/should be able to get this error message is if your PATH environment variable is empty or otherwise does not include your C:\Windows\System32 directory. You can test this by opening a Command Prompt, typing set PATH= and then trying to execute cmd. I do not know why this is your case but you must investigate.

@desun_evan Please post the actual error. It must be before the lines you posted.

I ran nmake this time...

cmd /c C:\qt_source\qtbase\src\corelib\mimetypes\mime\generate.bat mimetypes\mime\packages\freedesktop.org.xml > .rcc\debug\qmimeprovider_database.cpp

This is what I get when I use nmake after configuring Qt, how might I change cmd to cmd.exe if this is just a step in the nmake execution?

@JonB You're right cmd should also work. Most probably broken PATH.

@JonB I believe this was a path issue, thank you.
