No you don't. Thats the builddirectory, where the result of building
your application is put (including Makefile's, object files and what
not). The installation directory is something different, its the place
from where you and other users on the system will use the application.

That would install the sources, but I doubt you want that. You want to
list data files with INSTALL(FILES ...), the application can be
installed with INSTALL(TARGETS <app_target> DESTINATION bin)

Then when you run cmake you can say cmake
-DCMAKE_INSTALL_PREFIX=/usr/local/yourapp and cmake will install the
data files into that directory and the binary into
/usr/local/yourapp/bin when you run make install. That works the same
way as configure's --prefix option. (The default is /usr/local IIRC).
