Hi,

When linking ReCast, an open-source project, I got the following
errors.

-----error msg----

ld: library not found for -lSDL
collect2: ld returned 1 exit status
Command /Developer/usr/bin/g++-4.2 failed with exit code 1
-----end----

The project is configured with cmake-2.8.app.
The error says that the library "SDL" cannot be found. But I'm sure
that the SDL library locates in "-L/Users/mingzhang/Root/Project/
ReCast/recastnavigation-read-only/RecastDemo/Contrib/SDL/SDL.framework/
Versions/A ".
Why cannot it be found?

Any help is appreciated, thanks!
