- Simplify error checking when using execute_process.
- Set BUILD_SHARED_LIBS to OFF when building dependencies.
This is normally not needed, but msgpack interprets an unset
BUILD_SHARED_LIBS to build a shared library, which is the opposite of
the cmake behavior.
- Move function check_lua_module to Util.cmake.
- Remove unnecessary code.
- Make variable naming more consistent
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.
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.
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.
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.
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.
Change the default build type to always be Debug, and allow only four
predefined build types: Debug, Release, RelWithDebInfo and MinRelSize.
Furthermore, flags meant for single-configuration generator (make,
ninja) will not be used for multi-configuration generators (visual
studio, Xcode), and flags meant for multi-configuration generators will
not be used for single-configuration generators.
This will allow Debug builds to be built with MSVC which requires that
all dependencies are also built with the Debug build type to avoid
runtime library mismatch.
The correct way to specify build type (for example Release) for
single-configuration generators (Make and Ninja) is to run
cmake -B build -D CMAKE_BUILD_TYPE=Release
cmake --build build
while for multi-configuration generators (Visual Studio, Xcode and Ninja
Multi-Config) is to run
cmake -B build
cmake --build build --config Release
Passing CMAKE_BUILD_TYPE for multi-config generators will now not only
not be used, but also generate a warning for the user.

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/)
