I am so sorry. First time, I used grep "libwbclient", therefore I didn't see
that there is also wbclient.h and It should not be installed without
libwbclient.

include_HEADERS = \
    src/providers/ipa/ipa_hbac.h \
    src/lib/idmap/sss_idmap.h \
    src/sss_client/idmap/sss_nss_idmap.h \
    src/sss_client/libwbclient/wbclient.h \
                              ^^^^^^^^^^^
    $(NULL)
