Well, since you asked: it *would* be nice if cmake would know about the
headers needed by a target, or even support header-only targets. Currently
it feels like an artificial divide between shared object files and header
files:
# find required dependency which correctly sets up import targets:
find_package(BAR)
# additional step for headers (with side-effects for other targets)...
include_directories(${BAR_INCLUDE_DIRS})
# ... that is not needed (and in fact discouraged) for libs:
#NO: link_directories(${BAR_LIBRARY_DIRS})
target_link_libraries(foo bar)
To be fair though, most other build-systems are not any better at
handling header files. And since this feature request has already been
discussed in http://public.kitware.com/Bug/view.php?id=115, I'm content
with it only being deferred, not dismissed...
