Winver.h not found

I'm trying to compile Openglfreaks winestreamproxy (https://github.com/openglfreak/winestreamproxy) following his tutorial but the make script keeps punching out this error.

rmdir -- obj 2>/dev/null || : 
rmdir -- out 2>/dev/null || : 
mkdir -p -- obj 
. ./gen-version.sh && get_version && \
 output_version_defines >obj/version.h && \
 output_version_assignments >obj/.version 
mkdir -p -- out 
cp -LRpf -- obj/.version out/.version 
touch -- out/.version 
mkdir -p -- obj 
cat obj/version.h src/version.rc | wrc -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -DWIN32_LEAN_AND_MEAN=1 -DWINVER=0x0600 -D_WIN32_WINNT=0x0600 -DPSAPI_VERSION=2   -UNDEBUG -DNDEBUG=1  -o obj/version.res 

stdin:25:1: error: Unable to open include file winver.h 
make: *** [Makefile:95: obj/version.res] Error 1

I found that moving files that it is looking for from the include file in OS into the winestreamproxy file. It moves past the winver.h error. I keep doing this until this error stops me.
