So you're calling Fortran from C.

> CMakeFiles/hi.dir/hello.o -o hi -rdynamic -lgfortran
The problem is that CMake decides to use gfortran as a linker, not gcc,
because we specified that this is a Fortran project and forgot about C++.
So the solution is:
# To indicate that this is mixed language project
PROJECT(TEST CXX Fortran)
# To explicitly specify that your MAIN is C++'s main.
SET_TARGET_PROPERTIES(test PROPERTIES LINKER_LANGUAGE CXX)
"set_target_props" without "project" will not work.
