In the commit message you say:
> The custom command to copy the NodeJS executable was never being executed
Hm, seems it was for the other persons building webodf on windows. Any idea what might be different for you? @peitschie it worked e.g. for you before, did it?

execute_process will mean it is done every time make is called, no? but then file(DOWNLOAD ....) also is, so maybe not such a big problem. Not that I care much, as I live in the other side of the IF(WIN32) branch :)
