I'm updating a cmake build system for Linux to match our Windows (VS2019) compile options. Some of our projects use /Qip, others /Qipo. In the CMakeLists.txt file I have added -ip to CMAKE_Fortran_FLAGS_RELEASE (global compiler options for release builds). Some libraries have target_compile_options to add -ipo. This results in -ipo following -ip in the compiler options for those libraries. Is this going to behave as I would expect, with -ipo overriding -ip? The documentation seems to be silent on the subject. I'm working from analogy with the optimisation options (-On) in that the right hand most option is the one that applies for them.
