EIGEN_INITIALIZE_MATRICES_BY_NAN

[Frank Dellaert]

On http://www.alecjacobson.com/weblog/?p=3140 I read:

I always set the preprocessor symbol EIGEN_INITIALIZE_MATRICES_BY_NAN 
in the debug version of my code. That way uninitialised matrices seldom go unnoticed.

Can we do that, too ? Might make detecting errors much faster.

Add EIGEN_INITIALIZE_MATRICES_BY_NAN to Debug mode to resolve issue #184.

Great idea! Unfortunately you'll have to clear your CMake cache to get this in your Debug configuration.

[Frank Dellaert]

How do you clear that?

I just deleted my whole build folder, but deleting CMakeCache.txt should also do the trick.
