[Insight-developers] dependency checks

[Simon Warfield]

I was looking at the test_math.cxx code and it seems that the generated 
dependencies for test_math.o only list .h files.
If the .cxx file is changed, the build system doesn't appear to know 
that the .o file depends on that and needs to be updated.

How can I specify that test_math.o should be rebuilt if test_math.cxx is 
altered ?
