You seem to have include dirs for windres, that include spaces.
Remove them and try it again.
If you use standard C::B sources, they are most likely set in the global compiler settings ("Settings -> Compiler and debugger -> Global compiler settings -> [your_compiler] -> Search directories -> Resource compiler".
Only use global compiler settings, if you really know what you do, and if you need them for every project you want to compile with this compiler.
