The problem is that CMake does not call the linker. It invokes the linker by calling the compiler and passing flags through it.
In the module, Darwin.cmake, you find: SET(CMAKE_C_LINK_FLAGS "-Wl,-headerpad_max_install_names") SET(CMAKE_CXX_LINK_FLAGS "-Wl,-headerpad_max_install_names") But in Darwin-icc.cmake, you find: SET(CMAKE_C_LINK_FLAGS "-headerpad_max_install_names") SET(CMAKE_CXX_LINK_FLAGS "-headerpad_max_install_names") Changing the latter to match the former should fix the issue. However, IMHO, a correct implementation would either call the linker directly or "escape" the flags (with the "-Wl," prefix) so that they get passed correctly.
