Catching the needed information and the state machine is split.
gbuild-to-ide only finds 27 of 93 exe, due to the state machine
sequence:
     CXXOBJECTS for exe1
     CXXOBJECTS for exe2
     Recipe to execute for exe2
     Recipe to execute for exe1
only identifies exe2 and leaves exe1 without a project.

Solution is to have an array of state one for all pending exe.

This patch only contains the split
