I'm still stuck at this stage. I've tried doing this:

set_target_properties(qlom
        PROPERTIES
        LINK_FLAGS "${GLOM_LDFLAGS}")

But the linker flags then seem to be separated by ";" instead of spaces,
leading to error such as this:

c++: unrecognized option
'-pthread;-L/opt/gnome228/lib;-lglom-1.12;-lgiomm-2.4;-lgdamm-4.0;-lxml
++-2.6;-lgio-2.0;-lgmodule-2.0;-lgda-4.0;-lgthread-2.0;-lrt;-lxml2;-lglibmm-2.4;-lgobject-2.0;-lsigc-2.0;-lglib-2.0'

Surely there must be a simple way to use pkg-config?


My full CMakeList.txt so far is here, in case it's helpful:
c++: unrecognized option
'-pthread;-L/opt/gnome228/lib;-lglom-1.12;-lgiomm-2.4;-lgdamm-4.0;-lxml
++-2.6;-lgio-2.0;-lgmodule-2.0;-lgda-4.0;-lgthread-2.0;-lrt;-lxml2;-lglibmm-2.4;-lgobject-2.0;-lsigc-2.0;-lglib-2.0'
