Anyone out there doing #cs50 and running check50 locally?
I'm running into this issue on the week 4 problem recover, but when I compile and run it myself it works fine...
Seems check50 can't find the binary it's building as the 127 exit code means command not found, but I have no idea why! 🤔️

Turns out I had the answer in a file I created when I started #cs50 !

Once I sourced this in my shell check50 is all green!

```
# to use this file run it like this: $ source setup-env.sh

export CFLAGS="-fsanitize=signed-integer-overflow -fsanitize=undefined -ggdb3 -O0 -std=c11 -Wall -Werror -Wextra -Wno-sign-compare -Wno-unused-parameter -Wno-unused-variable -Wshadow"
export LDLIBS="-lcrypt -lcs50 -lm"

# The following line required on fedora
export LD_LIBRARY_PATH="/usr/local/lib"
```
