cmake - Can not set the compiler flags for Fortran using Cmake

Question

I would like to use CMake to build fortran source codes. I use this command set(CMAKE_Fortran_FLAGS_DEBUG "${CMAKE_Fortran_FLAGS_DEBUG} -Wextra -g -O -Wall -Warray-temporaries -Wconversion -fimplicit-none -fbacktrace -ffree-line-length-0 -fcheck=all -finit-real=nan -ffpe-trap=zero,invalid,overflow,underflow") to set up compiler flags for debugging but it didn't work. So what is right way to set up the flags for compiling fortran code? I used the cmake version 3.17.0, GNU Fortran (Debian 9.3.0-20) 9.3.0 and Debian testing. The full CMakeLists is

project(Simcoflow Fortran)
find_package(MPI REQUIRED)
set(Fortran_COMPILER_FLAGS "-w")
set(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -w")
set(CMAKE_Fortran_FLAGS_DEBUG "${CMAKE_Fortran_FLAGS_DEBUG} -Wextra -g -O -Wall -Warray-temporaries -Wconversion -fimplicit-none -fbacktrace -ffree-line-length-0 -fcheck=all -finit-real=nan -ffpe-trap=zero,invalid,overflow,underflow")
set(CMAKE_BUILD_TYPE DEBUG)
set(HYPRE_INCLUDE_DIR /usr/include/hypre)
set(${PROJECT_NAME}_INCLUDE_DIR)
set(HYPRE_LIBRARIES /usr/lib/libHYPRE.so /usr/lib/libHYPRE_FEI.so /usr/lib/libHYPRE_struct_mv.so /usr/lib/libHYPRE_IJ_mv.so /usr/lib/libHYPRE_parcsr_ls.so)
