Follow-up to eb1da498d6. The workaround in
that case only works if md5sum is in users path. We work around this by
adding the directory with the md5sum shipped with luarocks to PATH.

The wintools executables are stored in a zip file, making it
inconvenient to bump these during releases. Instead, unpack the
executables in the deps repository and download each executable
separately.
Older gcc versions (4.x) require passing --std=c99 compiler flag to
prevent warnings from being emitted. Instead of setting it for each
dependency, it's easier to just pass the CMAKE_C_STANDARD flag to all
dependencies. This also prevents the scenario of us forgetting to set it
if we add new dependencies.
Problem:
When building with gcc 4.9.2, tree-sitter throws warning: "for loop initial
declarations are only allowed in C99 or C11 mode"
Solution:
set CMAKE_C_STANDARD option to 99
Since 0007aa50bd the build unsets all URL
variable immediately when USE_EXISTING_SRC_DIR is TRUE, which is
correct. However, this causes the function BuildTSParser to break down
as cmake functions aren't traditionally equipped to deal with empty
variables. Using cmake_parse_arguments fixes this issue.
We provide options such as "DEPS_BIN_DIR" for the user to set, but only
sometimes use them. This makes binaries and other files to be spread out
if the user defines a custom DEPS_BIN_DIR location.
This will reduce required boilerplate, but more importantly it will
automatically unset variables ending on URL. This will help people
needing to avoid to unset the URL variable each time a new dependency is
added.
It is possible that this may remove a non-download variable ending on
"URL" in the future, however, the risk of this is likely much lower than
the risk of someone forgetting to unset the variable.
- Remove unused code
- Use consistent casing. Variable names such as LibLuV_LIBRARIES is
needlessly jarring, even if the name might be technically correct.
- Use title casing for packages. find_package(unibilium) requires the
find_module to be named "Findunibilium.cmake", which makes it harder
to spot when scanning the files. Instead, use "Unibilium".
Previously, all targets were connected in one main target called
third-party in order to remove any potentially conflicting shared
library. We can make each dependency target independent of each other by
only removing shared libraries from luajit and msgpack in their own
targets, as only these has unwanted shared libraries.
Eliminates lua-client and non-static libluv as test time dependencies
Note: the API for a public lua-client is not yet finished.
The interface needs to be adjusted to work in the embedded loop
of a nvim instance (to use it to talk between instances)
This makes it easier to see that -D is referring to the entire
"<variable>=<value>", rather than only <variable>. It also help syntax
highlighters highlight built-in variables.
Also remove Libvterm-tbl2inc_c.cmake as it's not required. It's used to
generate files that are already provided by the Libvterm project by
default. It's also not really something we need to concern ourselves
with as it's more of an authoring tool for the Libvterm creator as
mentioned in
https://github.com/neovim/neovim/pull/21986#issuecomment-1403733054.
There are a number of cmake variables and cache variables that need to
be passed to all dependencies. This is not only cumbersome, but also
fragile as it's easy to miss adding or removing a flag from a dependency
by accident. Introducing a global variable that controls all builds
makes it much easier to handle our dependencies.
Also fixes the currently broken release workflow as we need to pass the
CMAKE_OSX_ARCHITECTURES variable to all dependencies built with cmake.
It's simpler to let cmake figure out what flags to add to each platforms
to create position independent code rather than handling it ourselves.
Also remove code that sets POSITION_INDEPENDENT_CODE property on SHARED
and MODULE libraries, as it's already on by default.
* build: various cmake refactors and simplifications
- Add STATUS keyword to message to ensure messages are shown in the
correct order.
- Remove DEPS_CXX_COMPILER as we don't rely on C++ for any of our
dependencies.
- Simplify how msgpack and luv configure options are constructed.
- Rely on the default installation for luv instead of manually passing
configure, build and install commands.
- Simplify return code conditional.
* build: remove CMAKE_OSX_ARCHITECTURES_ALT_SEP workaround
CMAKE_OSX_ARCHITECTURES_ALT_SEP was defined as a workaround to prevent
the shell from interpreting `;`, which CMake uses as a list separator.
However, the same thing can be achieved by instead passing
CMAKE_OSX_ARCHITECTURES as a cache variable instead, which is a more
idiomatic way of achieving the same thing.
* build: define CMAKE_BUILD_TYPE before adding it to BUILD_TYPE_STRING
The problem with the current setup is that CMAKE_BUILD_TYPE is defined
after BUILD_TYPE_STRING. BUILD_TYPE_STRING will then be empty on the
first run, meaning that dependencies are built without a build type.
However, since CMAKE_BUILD_TYPE is a cache variable its value will
persist in subsequent runs. On the second run BUILD_TYPE_STRING will
have the correct value, but it's a different value from the ones the
dependencies were built with. This will force some dependencies to be
built again.
Fixes https://github.com/neovim/neovim/issues/21672.
The default cmake installation process for dependencies that use cmake
on all platforms is in general more robust and less verbose, so we rely
on that if possible.
build(deps): disable shared library for libvterm
Problem:
Cannot build both static and share libraries for libvterm under Windows.
The static and shared library would have the same name "vterm.lib", thus there would be multiple rules to build the same target.
Solution:
Disable shared library for libvterm.
This makes it possible to use Ninja on Windows to build dependencies (2x speedup!).
But not for Release builds yet.

59d5f692f removed cmake.deps/cmake/DownloadAndExtractFile.cmake and
support for USE_EXISTING_SRC_DIR. The Ubuntu nightly PPA still relies
on USE_EXISTING_SRC_DIR functionality since it can't access the network
during the build.
Supplying an empty value for ExternalProject_Add()'s URL value appears
to provide the needed mechanism to avoid re-downloading when the sources
are already present. This is undocumented behavior, though, so it may
break in the future.
Now, if USE_EXISTING_SRC_DIR is set, the ExternalProject's URL variable
is unset, preventing the download and erroring out if the source doesn't
actually exist.
DownloadAndExtractFile.cmake was initially introduced as a workaround to
avoid the massive amounts of logs generated by the download progress.
This is not a problem anymore as ExternalProject_Add has had the
DOWNLOAD_NO_PROGRESS option since cmake version 3.1.
We don't support 32bit Windows anymore, so it's not needed. Also remove
TargetArch.cmake and related code as we don't need architecture
detection for the same reason.
