Exactly, I've seen also this because I've started experimenting to add
VS 2015 to the Appveyor build matrix (VS 2015 is used to compile soon
to-be-released Python 3.5 so we'll need that to build pymssql):

https://github.com/FreeTDS/freetds/compare/master...ramiro:ci-appveyor-visual-studio-2015

https://ci.appveyor.com/project/ramiro/freetds/build/246/job/2lgrjkmg2w5agf72#L307

I wonder if Visual Studio 2012/2013/etc has the same issue we know VS
2008/2010 don't because we have them in the matrix already.

Doesn't seem to be a Cmake problem, we are using an older version (but
not so much and certainly non-RC).

Haven't found one so far.

I've been able to extract the following information from the Appveyor
build slave VM though (the ability con connect via RDP to the slave is
super-useful in these cases):

Console excerpt:

build\CMakeFiles\CMakeError.log file excerpt (presence of msvcrtd.lib
is strange, we aren't performing a Debug build):
