Can't say any other tool I ever used did not have the same issue however.

Must I get latest form source? Or did I do above incorrectly. Also ExternalProject_add is not in : file:///C:/Program%20Files%20%28x86%29/CMake%202.8/doc/cmake-2.8/cmake-commands.html (Windows Install document tree) should it be or is it new? -- Brian J. Davis
