`GIT_REPOSITORY` will cause cmake to rebuild if local dependency
changes, which isn't the case for `URL`.
Also document how to test a different commits of a dependency.
This will reduce friction as developers no longer need to provide a hash
when testing out different commits.
To skip the hash check, set `DEPS_IGNORE_SHA` to `TRUE` in
`cmake.deps/CMakeLists.txt`.
- remove "ran-" prefix from touch files as it's redundant since the
they're already in the directory named `touches`.
- Include `contrib` when formatting with `make formatlua`.
- Use TARGET_FILE generator expression instead of assuming the
executable location.
- reuse logic that determines whether to use lua or luajit.
- add translations to the `nvim` target.
Makefile improvements:
- rename variable `CMAKE_PRG` to `CMAKE` to make it more consistent with
the builtin `MAKE` variable.
- stop propagating flags to generator. Users should use cmake for
non-standard use cases.
- remove `+` prefix from targets. If the user for whatever reason wants
to dry-run a target then they should be able to.
Problem: Lpeg requires Lua headers. Currently the include directories
for Lpeg are set only to the bundled deps folder, so if the user wants
to use system Lua/Luajit, Lpeg will not find the system headers and will
fail to build.
Solution: Add system Lua/Luajit include directories when USE_BUNDLED_LUA
and USE_BUNDLED_LUAJIT are turned off.
