-Wextra works in shell but not in bash script-CodePudding

I was using today a bash script to perform some things that I need to execute a code, and I encountered with the error in the title. In the bash script, the shell says -Wextra command not found, but if I execute the command by myself:mpicc -Wall -Wextra -pedantic -o ptmm PerfTestMM.c -lblas it actually works. So I was wondering, why this could be caused? In the shell and in the bash script the very same command was run:

CC=mpicc
CFLAGS=-Wall -Wextra -pedantic
CFILE=PerfTestMM.c
EXE=ptmm
$($CC $CFLAGS -o $EXE $CFILE -lblas)

Thanks to @Biffen for the answer, CFLAGS=... has to be CFLAGS='...'.
