[Insight-developers] Build Order Issues

[Hans Johnson]

All,

Sorry, I've miss diagnosed the problem.  The PRIMARY REAL issue is that I
must link against ITKReview not itkReview!

I still believe that the building of itkTestDriver  belongs in the Testing
tree, but it may not be necessary (still testing various options with clean
builds).

Sorry,
Hans

> Background:

> I am trying to build ITK with the new USE_TRANSFORM_IO_FACTORIES and
> USE_REVIEW.  After building I will be installing ITK to a new location, and
> then linking and building against the installed version.

> I'm developing software that requires both the NeuralNetwork readers, and
> the new transform factories.

> The Goal:
> ---------
> Since the TRANSFORM_IO_FACTORIES were backwards compatible, I don't want the
> end user programs (i.e. InsightApplications) to require explicit linking
> against the itkReview library based on ITK compile flags.
> 
> I was hoping that if USE_TRANSFORM_IO_FACTORIES was chosen, then by adding
> "TARGET_LINK_LIBRARIES(ITKIO itkReview)"  to Code/IO/CMakeLists.txt any
> external application that previously required linking to ITKIO would now
> also link against itkReview.

> The problem:
> ------------
> In the Code/IO/CMakeLists.txt, the ITKIO library is built, BUT so is the
> itkTestDriver executable that needed for testing.  The linking of the
> itkTestDriver program at this stage introduces an unnecessary link
> requirement that itkReview be built already.

> Solution?
> ---------
> A) Move the itkTestDriver executable building to the Testing/Code/IO tree,
> and only build it if USE_TESTING is defined.
> B) Build IO library after the itkReview Library
> C) Both A & B

> Please let me know there is a better solution.
