Yes, I believe that is the conclusion I've come to.  ;)

I tried that instead (used "develop" instead of "build") and still encountered 
the same link errors.  I can't use "--git-ignore" because the sub-projects 
will not be populated and there's nothing to build.

The command lines I've attempted in the pyside-setup2/ folder are:

  * python setup.py build --qmake=Q:\Qt\5.4.2\64_dll\bin\qmake.exe
    --openssl=E:\openssl_64_dll\bin --jom --jobs=4
  * python setup.py build --qmake=Q:\Qt\5.4.2\64_dll\bin\qmake.exe
  * python setup.py build
  * python setup.py build --qmake=C:\Qt\Qt5.5.0\5.5\msvc2013_64\bin\qmake.exe
  * python setup.py develop --qmake=Q:\Qt\5.4.2\64_dll\bin\qmake.exe

The Qt in the Q:\Qt\5.4.2\ folder referenced above is our own build of that 
version.  Those in the C:\Qt\ folder are the pre-built binaries provided for 
download.  In all cases, I get a link error of some kind (the 5.4.2 version 
has one link error, the 5.5.0 version generates a different link error).

Do you actually mean "jom" here?

I am in charge of doing this for my team, so it's not an issue for me.  I've 
got an environment set up for building Qt that's largely automated.  In fact, 
as I stated earlier, one of the Qt versions against which I am attempting to 
build was actually built by me.  Are you saying that removing that compiler 
switch (if I can figure out how) addresses the link error?

Ah, ok.  I've already reported my failures and opinions of the state of PySide 
v2 to the team, but I will try this branch and see if I can get any further.

Thank you very much for the response, Chris.
