Actually this should look like:
gfortran -c hello.f90
g++ -c test.cxx
g++ -lgfortran hello.o test.o -o test

You need to work only with sources. Forget about object files.
Here is your CMakeLists.txt:

CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
PROJECT(TEST Fortran)

SET(TEST_SRCS test.cxx hello.f90)
 
ADD_EXECUTABLE(test  ${TEST_SRCS})
TARGET_LINK_LIBRARIES(test  gfortran)


# NOT NEDDED: SET_TARGET_PROPERTIES(hi PROPERTIES LINKER_LANGUAGE C)
# NOT NEEDED: CMAKE_EXE_LINKER_FLAGS: -lgfortran -o
# Only if you have one more fortran compiler: CMAKE_Fortran_COMPILER: /usr/bin/gfortran
# NOT NEEDED: CMAKE_Fortran_FLAGS: -c

Compiled executable now is in build directory. In your case it should
be in current directory.
 
Please, reply to all, so CMake mailing list gets also included.
