On my Linux system, I can look up the Linux and Windows ifort build rules in

/usr/share/cmake-2.4/Modules/Platform/Linux-ifort.cmake and
/usr/share/cmake-2.4/Modules/Platform/Windows-ifort.cmake .

The order you refer to above seems to come from the latter file.  Assuming
you have a windows system, you will have to find that file and change the
order to what you want.  And once that works, send the patch to the
list so it can be made a permanent CMake change so you don't have to
apply the change to every new version of CMake that you build.
