説明
Using meson-0.43.0, ninja-1.8.2, gcc-7.2.0
Building glib-2.54.3 with lto as per below results in the following library sizes for libgio-2.0.so.0.5400.3 (stripped)
1,419,000 bytes with configure/make 1,525,688 bytes with meson/ninja
i.e. about 100kb or 10% larger with meson/ninja
from "ninja -v", it appears that lto is being used at link time, but maybe this isn't the case?
