for some odd reason it says

'meson' is not recognized as an internal or external command,
operable program or batch file.
after entering

meson setup build-debug

i have but im not sure if i missed one

Edit:
ok so 

cd /d [wherever you keep your repositories]
git clone https://github.com/The-Powder-Toy/The-Powder-Toy

Part it looks like it just downloads TPT source file so i just skipped it since i was trying to compile the biology mod soure file and i already had the source file downloaded and ready but in both uses 

meson setup -Dbuildtype=release
didnt work and
meson setup build-debug
didnt work with the same error meson wasnt recognized
i will retry if this works but i think i missed 

python -m pip install --upgrade pip
pip install --upgrade meson ninja

So ima edit this again if it works
