`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`.
- add EXTERNALPROJECT_OPTIONS variable to main build
- use `REQUIRED` keyword for IWYU.
- remove check_c_compiler_flag checks when `ENABLE_COMPILER_SUGGESTIONS`
is `ON`. If we explicitly enable it then we probably want it to give
an error if it doesn't exist, rather than silently skip it.
- Move dependency interface libraries to their find module and use them
as a pseudo-imported target.
- Remove BUSTED_OUTPUT_TYPE. It's not used and we can reintroduce it
again if something similar is needed.
- Use LINK_OPTIONS intead of LINK_FLAGS when generating the `--version`
output.
Cmake 3.28+ will fail if two projects download the same file to prevent
scheduling problems. This can be circumvented by downloading luajit to a
unique location for each target. This is theoretically non-optimal since
we need to download the same file three times for universal builds, but
universal builds are rare and the convenience of this method outweighs
setting up the dependencies optimally. This fixes the currently broken
release workflow for mac.
Closes https://github.com/neovim/neovim/issues/26526.
Ensure bundled libraries and include directories are always searched
first before any others. This will provide a more consistent experience
as the search order of the builtin find_ functions can vary depending on
system. This should make the build process faster when building with
bundled deps as we limit the search to only the .deps directory.
Separating the search between .deps and everything makes debugging
find_-related problems simpler if you need to check how dependencies are
found.
For libraries, we divide the search process into the following order:
1. Only search in .deps directory and only search for static libraries.
2. Only search in .deps directory and search for all libraries.
3. Search everywhere and search for all libraries.
Make an exception for FindLibintl.cmake as changing the search order
seems to break some tests on macos.
Switch to a rolling release, so the `0-beta3` suffix is dropped in favor
of the date. Remove the custom UNIX command as the symlink is now
created by the LuaJIT Makefile.
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.
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.
Use the same logic for both deps (including LuaJIT, for which setting
this variable is mandatory) and Nvim: either the eponymous environment
variable if set, or the current software version if not.
Removes annoying warnings when building locally on macOS.
Problem:
Dirs "config", "packaging", and "third-party" are all closely related
but this is not obvious from the layout. This adds friction for new
contributors.
Solution:
- rename config/ to cmake.config/
- rename test/config/ to test/cmakeconfig/ because it is used in Lua
tests: require('test.cmakeconfig.paths').
- rename packaging/ to cmake.packaging/
- rename third-party/ to cmake.deps/ (parallel with .deps/)
