Re: Add custom flags to nimble install

[vitreo12]

Unfortunately, your approach doesn't work because most of the flags that 
`-d:danger` activates/deactivates are set in `nim.cfg`. In fact, if you look at 
the binary size of your `hi.nim` file compiled with your method and with the 
standard `nim c -d:danger hi.nim`, you'll see that the latter one will be 
smaller in size, because it will have all the `-d:danger` flags properly 
activated, getting rid of debug stuff, dead code, etc...
