The MSVC compiler/linker solves this by using a sort-of "here" document:

link32 @tmp_file_with_the_commands

Check the CMake module for the MSVC compiler(s) to see how it is done in 
the context
of CMake and apply that to the module used in the MingW32 case. (Well, 
this is
a rough sketch only ;))
