Building Seafile-Client on windows with using cygwin

Question

I try to building seafile-client on windows with using cygwin. When i call ./configure command it detect build system as Linux

...
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... yes
checking whether to build static libraries... yes
checking for special C compiler options needed for large files... no
checking for _FILE_OFFSET_BITS value needed for large files... no
checking for WIN32... no
checking for Mac... no
checking for Linux... compile in linux
checking for uuid_generate in -luuid... yes
found library uuid
...

it configure successfuly but when i call the make command it occur a lot of error. I guess it's because of it detect the build system as linux, but i think it must be windows. How can i do for solve this?

make error output:
