xdg-open: command not found on Windows

[rossivalen]

Hi, as per title tikzmake.sh doesn't work properly on Windows 10.
To make it work i added another line for the corresponding command to xdg-open on windows, that is:
else if:
start 1$.pdf

i changed to:

if [[ "$OSTYPE" == "darwin"* ]]; then
    open $1.pdf
elif [[ "$OSTYPE" == "linux-gnu"* ]]; then
    xdg-open $1.pdf
else
    start $1.pdf
fi
