[CMake] Library file not compiling

[John Dey]

Hi List,

I'm new to cmake and need a little help:

When I make from the root of the binary tree, I get the error below.   
Yet when I go the subdirectory clthreads, make from that dir creates  
the lib. Returning to the root and remaking eliminates the error.   
What am I missing?

aeolus_build $ make
make[2]: *** No rule to make target `clthreads/libclthreads.dylib',  
needed by `Aeolus'.  Stop.
make[1]: *** [CMakeFiles/Aeolus.dir/all] Error 2
make: *** [all] Error 2

I am using OSX 10.5 with a intel chip.  Any direction would be greatly  
appreciated.  Thanks.

John
