bandithedoge: Someone just passed me a link to your software, what a coincidence!
Unfortunately it doesn't build for me:

nix profile install github:bandithedoge/misstrhortion?submodules=1

In NixOS, there's a bunch of packages, that do:

substituteInPlace CMakeLists.txt \
  --replace-fail 'juce::juce_recommended_lto_flags' '# Not forcing LTO'

because those packages don't build otherwise.

I found out that they also build if I use -ffat-lto-objects.
It seems to me, the latter should result in faster binaries.
Is that correct?
Can anyone think of a better way to solve this?
