[Cmake] Dependency problem

[William A. Hoffman]

Well, cmake can either build things in sub directories first, or in the 
current directory.
We picked current directory first to support sub directories that contain 
tests that use
libraries from the parent directory.    If a library does not exist, and 
cmake is being run
the first time, cmake has rules that will jump into the library directory 
can build it the first
time.   However, once the library exists, cmake does not jump into the 
directory and try
a build before using the library.

In short, you will have to move your executable into a sub-directory.
