Did you use the skel generator script or the zip file with the examplesandbox? I remember that there were some issues with the generator that I fixed in [9570]. I forgot to update the ZIP file in the tutorial and just did this.I used the skel generator script for the sandbox establishment and its still a problem.
Ah, I think I remember now...There are issues with targets being inherited from parent trees. I think this mostly concerns XCode but not Visual Studio, but I could be wrong.
There is a thread on this on the CMake mailing list and it appears to be a limitation in XCode or the XCode CMake generator.
http://www.cmake.org/pipermail/cmake/2011-April/043794.htmlMy recommendation is to open the root project and build one target which will build all forwards. We are currently working on updating the library such that not forwards are required but will need to write some more tests so we can make sure that this change does not actually break anything...
