Wrapping/Generators ignore ${MyModule}Targets.cmake

[phcerdan]

I faced this with the module Eigen3 and now with ITKTotalVariation.

I export the dependencies into the ./lib/cmake/ITK-5.0/Modules/Targets/TotalVariationTargets.cmake with a call of itk_module_target(${third_party_lib}) in the external module.

That target file is used by apps using the module, however, the python wrappings are ignoring it.

I haven't found any reference to the targets file in the CMake related to wrapping. It would be extremely helpful to have it!

The targets file is referenced in the module info file (i.e. lib/cmake/ITK-5.0/Modules/TotalVariation.cmake), so it would be a matter of reading it from there in the wrapping/generator module.

@thewtex @fbudin69500 if you have any hint on this would be great. I haven't found yet how/where the wrapping/generators interact with modules, but will have a look if I find more time!

@phcerdan is this issue still valid?

[phcerdan]

It is valid, however, a workaround was merged in #707 . We can close it.
