[CMake] getting undefined error to my own libs.

Just put the implementation of the template class in the declaration. Get 
that to work, then try to get fancy if you want to.

ok, I've read the links, let say I'm not use the export option, when I 
look at the how to avoid link errors here: 
http://www.parashift.com/c++-faq-lite/templates.html#faq-35.13 I see that 
what I've did is the same, isn't it? 
I'm not sure where to follow from here... if I've did what they say and I 
still get a undefined error, then I must have miss configured cmake.
when I add extern to the deceleration in the header, I get this error: 
storage class specified for `Array`
