For many of the projects I have I have exactly the same structure

src/a
src/b
src/c

and installing from some or all of these sub-directories
using the install command in the CMakeLists.txt of the
sub directories does not pose any problem with cmake.

If the install from a certain subdirectory is missing (src/xml
in your case) I would suggest you carefully check the CMakeLists.txt
of that directory. Chances are you made an error there.
