Using the preprocessor before generating prototypes provides some
"niceties" but the places that rely on these are pretty few.
Vastly simplifying the BUILD SYSTEM is a better trade-off.
Unbalancing { } blocks due to the preprocessor is cringe anyway (think
of the tree-sitter trees!), write these in a different way.
Add some workarounds for plattform specific features.
INCLUDE_GENERATED_DECLARATIONS flag is now technically redundant,
but will be cleaned up in a follow-up PR as it is a big mess.
Copy whatever was made to work for generated headers:
(1) we need to consider all cmake targets not just main_lib
(2) we need to add the sysroot for macOS
${CONFIG} is an empty string even when configuration is known at
configuration time. $<CONFIG> has to be used at "generation time"
Currently zig's reimplementation of cmake config headers does not
support $<CONFIG> so use a branch to pick the one which works.
NEW BUILD SYSTEM!
This is a MVP implementation which supports building the "nvim" binary,
including cross-compilation for some targets.
As an example, you can build a aarch64-macos binary from
an x86-64-linux-gnu host, or vice versa
Add CI target for build.zig currently for functionaltests on linux
x86_64 only
Follow up items:
- praxis for version and dependency bumping
- windows 💀
- full integration of libintl and gettext (or a desicion not to)
- update help and API metadata files
- installation into a $PREFIX
- more tests and linters
