FWIW, libGLX.so.0 was included in our x86_64-linux asy binaries for at
least the last few years ...

$ ldd /usr/local/texlive/2022/bin/x86_64-linux/asy|fgrep libGLX
libGLX.so.0 => /lib64/libGLX.so.0 (0x00007fd9e5a2b000)
$ ldd /usr/local/texlive/2021/bin/x86_64-linux/asy|fgrep libGLX
libGLX.so.0 => /lib64/libGLX.so.0 (0x00007f041cf99000)
$ ldd /usr/local/texlive/2020/bin/x86_64-linux/asy|fgrep libGLX
libGLX.so.0 => /lib64/libGLX.so.0 (0x00007f6bf0dd6000)
