Unable to build JSBSim source on Windows using Cygwin

I am trying to build JSBSim sources on the following webpage. I have already configured sitl simulator and wanted to run JSBsim with it.

http://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html

I had some missing packages when I did

cmake …

I resolved it by downloading some packages. My cmake … command output is as follows.

$ cmake …
– Configuring done
CMake Error at python/CMakeLists.txt:86 (add_custom_command):
Error evaluating generator expression:

$<IF:$<BOOL:>,--config,>

Expression did not evaluate to a known generator expression

– Build files have been written to: /cygdrive/c/users/Ujjwa/ArduPilot/jsbsim/build

After that I ran make command to and I am getting errors in some files. The first part of the error looks something as follows.

/ArduPilot/jsbsim/src/simgear/io/iostreams/sgstream.cxx:39:41: error: no matching function for call to ‘sg_ifstream::open(const wchar_t*, std::ios_base::openmode&)’
