Installing source package on Windows fails with parallel make

[wch]

On my Windows machine, my ~/.Renviron contains MAKEFLAGS=-j4. When installing the source package, it fails, because it tries compiling package code before the openssl library is downloaded and unzipped. Commenting out MAKEFLAGS=-j4 makes the problem go away.

The same thing happens with install_github().

To fix it, the dependencies should be specified differently. We had the same problem in rstudio/websocket#43, and have a potential fix in rstudio/websocket#44.

Same heree

I'm not sure I would recommend using parallel make with the current toolchain (the version of make is about 15 years old) but I'll have a look....
