CMake compile options

[webisu]

In the top level CMakelLists.txt

if(CMAKE_Fortran_COMPILER_ID MATCHES "^(Intel|IntelLLVM)$")
set(CMAKE_Fortran_FLAGS "-g -traceback ${CMAKE_Fortran_FLAGS}")
set(CMAKE_Fortran_FLAGS_DEBUG "-O0")
elseif(CMAKE_C_COMPILER_ID MATCHES "^(GNU|Clang|AppleClang)$")
set(CMAKE_Fortran_FLAGS "-g -fbacktrace ${CMAKE_Fortran_FLAGS}")
set(CMAKE_Fortran_FLAGS_DEBUG "-ggdb -O0")
endif()

has no effect on the actual compile options. Neither does add_compile_options().
However, if you copy the above code fragment to wgrib2/CMakeLists.txt then the
compiler options are enabled. Seems that

set(CMAKE_XXX_FLAGS,...)
only works for that directory.

cmake version 3.22.1

Moving the cmake code that sets the compile options from CMakeLists.txt to wgrib2/CMakeLists.txt.
Merged some of the compile options from the pre-github version of wgrib2 concerning the math model.
