<p>Your <code>jjacobsohn</code> account runs on a new environment
where build workers have Visual Studio 2015 installed.
<code>JoakimSoderberg</code> account still runs on Azure where
workers don't have VS 2015.</p>
<p>There is a difference:</p>

<p>The question - is there any way to force it building for VS
2013?</p></div>Feodor Fitsnertag:help.appveyor.com,2012-11-13:Comment/373684312015-07-14T15:05:09Z2015-07-14T15:05:09Zcannot build project with opencv<div><p>Setting the os-Property in the appveyor.yml file to unstable
seems to fix the issue, but I don't think that's a permanent
solution (?).</p></div>Johann Jacobsohntag:help.appveyor.com,2012-11-13:Comment/373684312015-07-14T16:41:59Z2015-07-14T16:41:59Zcannot build project with opencv<div><p>Yes, you just switched to an image without Visual Studio 2015.
But VS 2015 is going to be released pretty soon and many developers
will have it installed along with VS 2013. I don't believe that
build can't be forced to use VS 2013 instead of using the most
recent VS found. Have you tried contacting the author of that
library?</p></div>Feodor Fitsner
