Might be caused by JuliaLang/julia#25459

[blegat]

@aritrasep Let me know if #160 fixes the issue

@blegat I was able to successfully build CPLEX.jl, however now I am getting the following error when using CPLEX:
ERROR: LoadError: LoadError: syntax: ccall argument types must be a tuple; try "(T,)" and check if you specified a correct return type
