I'm afraid we don't understand what you're asking.  What program in the
toolchain do you want to access a 5 GB file?  CMake? make? The compiler?
The program that is compiled?

If you just want your software compiled with the proper flags to enable
64-bit fseek operations, then you can add the flags yourself to
CMAKE_C_FLAGS and CMAKE_CXX_FLAGS.  If building your software requires
these flags and will not work without them, then it is possible to write
CMakeLists.txt files that automatically add the flags by detecting the
compiler being used.
