Adding the installation directory to the search path is dangerous on 
Windows and can result in an empty path when the length exceeds some 
limit: 
https://stackoverflow.com/questions/43014724/how-to-reset-system-variable-path-after-tesseract-installation.

In addition I don't like having a global path setting with lots of 
entries for many different programs. That can cause ambiguities if 
different path entries include incompatible EXE or DLL files with the 
same name. Windows uses PATH not only for finding EXE files but also for 
DLL files.

Therefore I would not implement the suggested feature.

I suggest running the QEMU executables by specifying their full name 
including their installation directory. And it's also easy to add a 
local batch file which sets the right path temporarily.
