What about:
mex generateEllipseCandidates.cpp libmwlapack.lib libmwblas.lib ...
and omit "-lC:/MATLAB/R2013a/extern/lib/win64/libmwlapack.dll"

Did you consider my suggestion? My code does not "omit the lib path", but add the library explicitely. Please post, which command produces the show error message.
