OK,
Here is my test code:
set(op_mod "ITKReview")
find_package(ITK REQUIRED OPTIONAL_COMPONENTS ${op_mod})
message("ITK_${op_mod}_FOUND: ${ITK_${op_mod}_FOUND}”)
I’m running CMake 3.6.2. According to this documentation [1], I expect the
above variable to be set if the component is available or not. Here the output:
ITK_ITKReview_FOUND:
So it appears these per-component variables are not being set. I thought I’d
first test this with an internal module before checking an installed external.
How do I optionally use ITK components? How do I know what components are
available in an installed ITK?
Thanks,
Brad
