I assume the content of the .hpp is between #ifndef CARRAY_HPP
then the code is the .cpp file.

The trouble comes from the fact that your class is a template one,
so that the content of the .cpp file may not be compiled independently
"as-is" because it must be instantiated first.

I invite you to read this:
http://www.parashift.com/c++-faq-lite/templates.html#faq-35.12
and may be this one too:
http://corfield.org/index.cfm/event/cplusplus.section/section/ptexp

Note that the "export keyword" solution may not be a good one
because many compilers do not implement it, beginning with gcc:
http://gcc.gnu.org/bugs/#nonbugs_cxx

I think may be you did not played a lot with templated classes.
(just a guess I may be wrong).

Concerning this issue, I'm pretty sure this is not a CMake one.
