I've added gtkmm with the following .mk file (with no errors):
#####################################################
LIBGTKMM_VERSION = 2.24.0
LIBGTKMM_SOURCE = glibmm-$(LIBGTKMM_VERSION).tar.bz2
LIBGTKMM_INSTALL_STAGING = YES
LIBGTKMM_CONF_OPT = --enable-shared
LIBGTKMM_DEPENDENCIES = libglib2 host-pkg-config

$(eval $(call AUTOTARGETS))

the when I try to compile a gtkmm helloworld example I get this error:

Perhaps do I install those *mm library manually one by one?
