CMake support the F extension.

The point is: 
"You have called ADD_LIBRARY for library ukmoradlib without any source files. 
This typically indicates a problem with your CMakeLists.txt file"

Your script above does
{{{
add_library(ukmoradlib STATIC ${ukmorad_SRCS})
..
set(ukmorad_SRCS
  ${ukmorad_main_SRCS}
  ${ukmorad_ses_setup_SRCS}
  ${ukmorad_common_SRCS} 
  ${ukmorad_ses_flux_calc_SRCS
)
set(ukmorad_main_SRCS ..
}}}

This results in ${ukmorad_SRCS} being nothing when evaluated in:
add_library(ukmoradlib STATIC ${ukmorad_SRCS})

You have to set the variables _before_ you use them:
{{{
set(ukmorad_main_SRCS ..
..
set(ukmorad_SRCS
  ${ukmorad_main_SRCS}
  ${ukmorad_ses_setup_SRCS}
  ${ukmorad_common_SRCS} 
  ${ukmorad_ses_flux_calc_SRCS}
)
add_library(ukmoradlib STATIC ${ukmorad_SRCS})
}}}

set the FC environment variable.
