Well, you're doing a lot of things that aren't valid CMake syntax, that might
be part of the problem.
Just a few:
* ${Imath_ROOT} is not the same as ${imath_ROOT}
* ${blah}include is going to be wrong because you probably need a slash between
them?
* The commas in target_link_library are all wrong, CMake simply does not use
commas to separate function arguments at all.
I would expect the right modern idiom to look like this:
find_package(Imath REQUIRED)
target_link_libraries(${app} PRIVATE Imath::Imath)
