May be you could put a CMakeLists.txt in each subdir
such that:

in the parent folder you could:

set(SUBDIRS "archive;models;whatever")
foreach(SD IN LISTS SUBDIRS)
  add_subdirectory(${SD})
endforeach()

then inside each directory:

get_filename_component(CDIR ${CMAKE_CURRENT_SOURCE_DIR} NAME)
set(filelist "commentitemsmodel.h gameitemsmodel.h highscoresmodel.h")
install(FILES ${filelist}
          DESTINATION ${INCLUDE_INSTALL_DIR}/gluon/player/lib/${CDIR}
          COMPONENT Devel)


The latest CMakeLists.txt (the one in the subdir) is almost always the
same and could
be generated with a minimal script.

Not sure whether if it's better than your current solution.
May be it's a little less painless to write.
