modifying Makefile for silverfrost FTN95 ( Windows) - makefile

Question

Compiling error
I am quite new to Fortran coding.
Currently, I have a makefile which has been previously used by original authors to compile the Fortran codes in Linux. However, I cannot understand what needs to be changed in the previous makefile to run it in Windows-based compiler Silverfrost FTN95.
While trying to compile in FTN95 I encountered the following error:
C:\Users\Geo-TGS\Documents\landslidemodel\src\TRIGRS>MAKE TPX
mpif90 -w -O3 -w -O3 -c ssizgrd.f95
process_begin: CreateProcess(NULL, mpif90 -w -O3 -w -O3 -c ssizgrd.f95, ...) failed.
make (e=2): The system cannot find the file specified.
makefile:59: recipe for target `ssizgrd.o' failed
MAKE: *** [ssizgrd.o] Error 2
C:\Users\Geo-TGS\Documents\landslidemodel\src\TRIGRS>make trg
mpif90 -w -O3 -w -O3 -c grids.f95
process_begin: CreateProcess(NULL, mpif90 -w -O3 -w -O3 -c grids.f95, ...) failed.
make (e=2): The system cannot find the file specified.
makefile:59: recipe for target `grids.o' failed

What changes need to be made for the code to compile?
