[Insight-developers] Dual Purposing ITK External Module

[Xiaoxiao Liu]

Brad,

 An external module is nothing but an internal module that is not checked
into the ITK source repository.  If the code base needs to be standalone and
have different testing setup, it is more of an "app" to me, which could have
different directory structures and CMake configurations.

 I put all my local modules in the source tree under Modules/External and
utilize all the modular itk CMake macros.

 You probably could have dual functionality by  putting several "IF"
statement to switch between "module" mode and " app" mode. But it probably
better to choose one mode.
