Have you considered using the CMakeLists.txt provided in libsquish, and
therefore use the cmake-package infrastructure? It should properly
handle the shared vs. static library case, and reduce the amount of
manual stuff that you need to do in LIBSQUISH_INSTALL_STAGING_CMDS and
LIBSQUISH_INSTALL_TARGET_CMDS.

Thanks!

Thomas
