[CMake] race condition with target_objects

[Juan E. Sanchez]

Hi,

The likely problem is that the symdiff_objects and the symdiff_tcl are 
in side-by-side directories.  They are both added using ADD_SUBDIRECTORY 
one level up.  If I put symdiff_python before symdiff_tcl, then that 
target will fail.  Please fix your Makefile generator.

Regards,

Juan
