Error Loading liblsl Library

[SalIITGN]

I am trying to run a program from liblsl-Matlab to send strings. However, I am receiving the error: "Error loading the liblsl library: Undefined function 'lsl_loadlib_' for input arguments of type 'char'. Make sure liblsl-Matlab/bin is added to path and try running build_mex.m'

The directory has been added to the Matlab path. I would be thankful for any help. (I am using Windows platform.)
