Problem installing libcurl on qnx momentics

I’m trying to install the libcurl package on my qnx momentics IDE (the host is a windows machine). All the documents that explain how to install packages, say that you need to use qnxinstall…well I’ve tried that but qnxinstall doesn’t exist on my machine…
Can anybody tell what I’m doing wrong ???

Those packages, as well as the package installer (qnxinstall) are for self hosted QNX environment. Unfortunately, it won’t work for your cross platform development environment from windows.
