Search Directory - Global working, Project-Only not working

[GuardWaffle]

Hello,

I am trying to add a search directory ("...../include") to my project, but the compiler does not seem to notice it.
When I add the directory to the global search directories (Settings > Compiler > Search directories) it works fine, but when I add it to the project specific search directories (Build Options > Search directories) the compiler won't recognize it. I tried adding it to the project build options, the target build options and both at the same time, but neither seems to work. I also tried prepending or appending target options to project options but this is not helping either. Do you have any idea what may cause this? If you need additional information please let me know.

Thanks.
