CPLEX binaries are not allowed to be placed in folder with general name

[JorgeGarciaCastillo]

In file build.jl there is the following code:

wincpxvers = ["126","1261","1262","1263"]
if is_windows()
    for v in reverse(wincpxvers)
        env = "CPLEX_STUDIO_BINARIES$v"
        if haskey(ENV,env)
            for d in split(ENV[env],';')
                contains(d,"cplex") || continue
                if v == "126" # annoying inconsistency
                    push!(libnames,joinpath(d,"cplex1260"))
                else
                    push!(libnames,joinpath(d,"cplex$(v)"))
                end
            end
        end
    end
end

The line contains(d,"cplex") || continue forces the path to contain exactly the word cplex, which I believe is not necessary. The only file needed is the .dll with could be placed in an arbitray folder

We'll accept pull requests if you present a clear use case. Why wouldn't the cplex path have "cplex" in it?
