Flatpak build (#4175)

* Initial commit for the builder

* fix wx, use hack to install into /app

* add some workarounds for /usr/local

* fix up rest of paths

* attempt to fix wxwebview undef

* figure out why wxwidgets isnt getting its patches applied

* do "proper" patching of wxwidgets

* Flip the flag

* actually append the /usr/local

* restrict package finding to flatpak only

* Update the destdir stuff for mpfr, gmp

* Transfer over all the _destdir, again

* update patch command for all other plats

* initial ci check

* what even happened

* clear ci image

* I doubt this will do anything

* do cleanup after running each step

* remove build objects for flatpak ci

* compress debug info

* Fix MacOS build

* Try saving space after building deps

* No debug info for now

* Do debug info, use thin static archives

* use BSD flag, not --thin

* try building with lto

* Use release, no debug info

* remove lto

* Revert the last 5 commits

* It might require write perms

* Revert "It might require write perms"

This reverts commit 44cec58a5713cb5ebbc44e64e314b88b553b8f75.

* Import fixes for merge

* remove some patch stuff

* the worst hack!

* remove uneeded patches

* Initial commit for the builder

* note to self, go back to regular wx

* attempt to fix wxwebview undef

* do "proper" patching of wxwidgets

* update patch command for all other plats

* what even happened

* -ldep_name-NOTFOUND is still here

* concat patches

* Build wx with flatpak

* more wx shenatigans

* fix a missing import

* build wx with proper flags

* fix imports and libs

* trigger ci

* try fixing mac and windows ci

* remove duplicate definition of freetype

* curl may not have openssl for a dep

* has openssl been found?

* force building

* build images on apple

* cleanup for review

* cleanup cmake files
