The CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGS setting has always been meant for flags needed to export symbols from executables for use by shared library plugins. Since commit v3.4.0-rc1~58^2~1 (CMP0065: Restrict the use of CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGS, 2015-08-24) this is made explicit by using the flags only for executables with ENABLE_EXPORTS, guarded by CMP0065 for compatibility. On some platforms we were accidentally using this setting to pass other flags to the linker: * AIX: -bnoipath, -brtl * HP-UX: +s, +nodefaultrpath These flags are incorrectly dropped when CMP0065 is set to NEW. Fix this by moving the flags to more appropriate places for linking executables.
