getting this error in both header files

Element ‘1’: conversion from ‘int’ to ‘bool’ requires a narrowing conversion

I would like to know if I should be using the ITK header files from within the SITK code, or from the ITK library itself?

I changed the code from std::vector m\_WhichDimensions{ std::vector(3, true) }

to

std::vector m\_WhichDimensions{ true, true, true };
