# So the story here is that -Wl,-no-needed is a default linker flag on only on Ubuntu
# (debian or archlinux does not use this). This will exclude a lot of libraries from linking into
# executable.
# #ITK_LIBRARIES in a superbuild now contains the following libraries.
# "itkdouble-conversion itksys itkvcl itknetlib itkv3p_netlib itkvnl itkvnl_algo
# ITKVNLInstantiation ITKCommon itkNetlibSlatec ITKStatistics ITKTransform ITKLabelMap
# ITKMesh ITKMetaIO ITKSpatialObjects ITKPath ITKQuadEdgeMesh ITKIOImageBase ITKOptimizers
# ITKPolynomials ITKBiasCorrection ITKFFT ITKKLMRegionGrowing ITKOptimizersv4 ITKWatersheds"

# OTBITK module will find all of these components in Modules/ThirdParty/ITK/otb-module-init.cmake
# But due to default -Wl,-as-needed flag many of them are ignored.
# see the documentation of GNU ld -as-needed for details on this behaviour.

# Our problem is that we need these ignored ones in the some header-only modules.
# Eg: Modules/Core/LabelMap
# This module depends on ITKLabelMap but does not link with it as it doesn't create any module (lib, exe)
# All it use is a couple of headers from ITKLabelMap. So removing that dependency is out of question.

# At this point, possible solution are follows:
# 1. use -Wl,-as-no-needed to CMAKE_LINKER FLAGS and be done with it. (all executable contains many used libs)
# 2. glob all libITK*, libitk* in the package script. (ugly and I don't agree)
# 3. make a dummy executable and link that with all of OTB libs and use -Wl,-no-as-needed in that
# 4. pick one of the random test executable and only add -Wl,-no-as-needed to it. (still a hack)
# ..
# ...
# RK: I finally decided to go with 4th option.
# Take an existing test executable otbTestKernelTestDriver and force -Wl,-no-as-needed.
