how do i set quartus to compile VHDL to 2008, tool can't find library float_pkg

I am using quartus prime lite v 21.1 and trying to compile / synthesize and get error

10481 VHDL use Clause error: design library "ieee" does not contain primary unit "float_pkg"

If i look at the directory structure, these files do exist at :

C:\intelFPGA_lite\21.1\quartus\libraries\vhdl\ieee\2008

I tried to set this up in quartus doing tools->options->general->librairies

but this did not help anything, where do i go or how do i set up quartus to point to or use the vhdl 2008 libraries?

    VHDL2008 support is limited in the Lite edition. That might be what you are running into.

    Hello,


    You can add the VHDL-2008 Support Library to your project (files fixed_pkg_c.vhdl and fixed_float_types_c.vhdl) and add this declaration:

    library ieee_proposed;
    use ieee_proposed.fixed_pkg.all;

    The library is available at https://github.com/FPHDL/fphdl

    Cheers
