Perhaps by setting property LINK_INTERFACE_LIBRARIES to ""? Example follows.

/Hugo Heden


TARGET_LINK_LIBRARIES( mylib otherlib )

# http://www.vtk.org/Bug/view.php?id=3490 ..When other executables and
# shared libraries link to libmylib.so, they should not necessarily
# link to the stuff that libmylib.so linked to, just because
# libmylib.so linked to them. (That is otherwise the default in
# CMake). So we have to do this:
SET_PROPERTY( TARGET mylib PROPERTY LINK_INTERFACE_LIBRARIES "" )
