Install 7z.dll to libexec instead of bin.

[staticfloat]

This is required for 7z.exe to load properly. I believe this was not
caught in previous testing because if the bin folder is on the PATH,
this is not necessary, however we definitely cannot rely on that.

however we definitely cannot rely on that.

Possible to add a test by setting withenv("PATH" => "...")?

...I guess not then

No need to create merge commits for this type of 1-commit PRs imo.

Presumably that explains this test failure for Electron.jl on 1.3-rc4.1?

Having said that, shouldn't PkgEval have caught this?

[staticfloat]

Yes, this should be the reason why. You should replace that direct invocation with something like this:

7z_path = withenv("PATH" => string(joinpath(Sys.BINDIR, "..", "libexec"), Sys.iswindows() ? ";" : ":", ENV["PATH"]) do
	Sys.which(`7z`)
end
run(`\$7z_path ...`)

I am coding in Windows and get the same problem. There do be the 7z.dll and 7z.exe in the libexec folder. So how should I fix this?

Please open a new issue with the full error message you're seeing, and the version of Julia you're using.
