Cbc just does not have the recent ThirdParty/Glpk in the Externals.
You can change to stable/1.5, this should give you Glpk 4.37.
Or you take Osi 0.100.
However, since OsiGlpk uses the older glpk-interface, the feasibility
pump as introduced with 4.37 is not available, except if you patch the
glpk-sourcecode.
