Apparently the library only supports Win64 as the platform? Switched to that build config:

cmake -G "Visual Studio 14 2015 Win64" .

and we compile fine. However building via

cmake -G "Visual Studio 14 2015" .

produces the above error. Did I miss this in the documentation?

[phicore]

I build it under win32. You need to set alignement to 16bytes un the cmake generated solution

[wjakob]

@phicore: can you provide details how to do this? Perhaps it could be integrated into the default build file?

[wjakob]

never mind, fixed in fe1e8fd
