Windows installation a minor fix needed

https://blocksds.skylyrac.net/docs/setup/options/windows/ I tried to download on windows manually and it did work however, make would not work "From there, for example, go to graphics_3d/volumetric_shadow and type make. This will generate a NDS ROM that you can try with an emulator or a flashcart." The location of the file directory is /opt/wonderful/thirdparty/blocksds/core/examples/graphics_3d/volumetric_shadow I opened a Makefile and the directory was /opt/blocksds/core ... so I deleted /opt/ and make worked. I did not tried other installation options but I think maybe the file location is for linux? I guess so it did not work in Windows anyways I really like this project, I had a problem with DevkitPro as the recent version does not support external libraries and working only with libnds was such a mess.
