I removed libisimulate but i get a warning if i compile. What's wrong?

so I installed this: http://www.vimov.com/isimulate/ then i removed it because i didn't need it anymore. But now I get this warning every time I compile:

ld: warning: directory '/Users//../../Downloads/libisimulate-4.x-1.5-20100925-opengl' following -L not found

I deleted all. I searched for anything which contains "isim" with the finder and i did not find anything. What's wrong?

EDIT: And it says something with Project <App name> Conf开发者_运维知识库iguration Debug

XCode ld: warning: directory .. following -F not found To resolve this warning in XCode, browse the App Target Preference and look for library paths. Make sure you remove ant invalid search paths, rebuild. Warning should disappear.

ld: warning: directory '/some path' following -F not found

This worked.
