[CMake] Incorrect extra MinGW link flags

Thu May 19 11:53:43 EDT 2011

Sorry, usually there are errors when trying to generate project under
cygwin, but cmake uses backslashes.

Then I suggest looking at xmlparse and CE_FEMxml dependencies. Because
they're static libraries, CMake adds all their dependencies into link
command.
You can also check CMake's advanced variables and files in CMakeFiles. There
information about system is kept (along with linker and compiler's command
line templates).
