How is your cmake file being called? If it is being called with  
"include(...)" then basically your file contents is substituted for  
the "include(...)" call. So the file "includes.cmake" without any  
leading prefix directory makes sense that it can not be found.

You basically need to get the current directory that CMake is  
traversing to figure out what prefix to use.

Do you _really_ need to place the include(includes.cmake) BEFORE the  
project() command? If you can swap these two lines then you can do  
something like:

project (vfx)
include ( ${vfx_SOURCE_DIR}/includes.cmake ) and it should find the  
"includes.cmake" file in the same directory as the vfx CMakeLists.txt  
file.

Hope that helps.
