find_package(ITK 4.5 COMPONENT) corrupted by SEM

[hjmjohnson]

The CMakeLists.txt file below is a simple example that demonstrates that including SEM before ITK causes find_package(ITK COMPONENTS ) to be corrupted.

SlicerExecutionModel hash 865e2a7 does not seem to exhibit this behavior.

THIS FAILS

find_package(SlicerExecutionModel REQUIRED GenerateCLP)
include(${GenerateCLP_USE_FILE})
include(${SlicerExecutionModel_USE_FILE})
include(${SlicerExecutionModel_CMAKE_DIR}/SEMMacroBuildCLI.cmake)
message(STATUS "YYYY ${ITK_INCLUDE_DIRS}")

find_package(ITK 4.5 COMPONENTS

include(${ITK_USE_FILE})

else()

THIS WORKS

find_package(ITK 4.5 COMPONENTS
${ITK_MODULES_USED}
REQUIRED
)
include(${ITK_USE_FILE})
find_package(SlicerExecutionModel REQUIRED GenerateCLP)
include(${GenerateCLP_USE_FILE})
include(${SlicerExecutionModel_USE_FILE})
include(${SlicerExecutionModel_CMAKE_DIR}/SEMMacroBuildCLI.cmake)
message(STATUS "YYYY ${ITK_INCLUDE_DIRS}")

message(STATUS "XXXX ${ITK_INCLUDE_DIRS}")

endif()

Matt, I think you may also be interested in knowing about this funny behavior when using recent SlicerExecutionModel checkouts.

JC,

I think this most recent patch in SlicerExecutionModel breaks behavior of find_package(ITK 4.5 COMPONENTS XXXX).

The included CMakeLists.txt file demonstrates the bad behavior.

When SEM is found first, and ITK found second, the incorrect (severely truncated include paths) is present.

When SEM is second, then all seems to work OK.

@hjmjohnson Thanks for identifying the issue.

Assuming this is fixed.
