title: Where is GSL installed on cygwin, windows 10?
body: <p>I want to use GSL on Windows 10. After I install GSL packages in cygwin, I cannot find the install gsl folder under cygwin. The error is like this:</p>
  
  <p>$ g++ bessel.cpp -lm -lgsl -o bessel.out -L/usr/bin
  bessel.cpp:1:32: fatal error: gsl/gsl_sf_bessel.h: No such file or directory
  compilation terminated.</p>
  
  <p>though I do see the GSL packages installed:</p>
