>From the docs I take: "-p:PATH" => Add path to search paths"
So in my understanding a call of "nim -p:c:\tools\mingw64\bin ..." would add "c:\tools\mingw64\bin" to the contents of my %PATH% environment variable and thus search e.g. gcc.exe along the new %PATH% (i.e. <path>;c:\tools\mingw64\bin"). However, this doesn't seem to work. Is my assumption/understanding wrong?
