* Add meson support
* Modify zlib to be detected via pkgconfig in dependent rules
* Modify zlib and expat to be linked to shared libs in dependent rules
* Add example usage of Meson rule
This commit adds the glib library to the "examples" build. glib requires
pcre2, so pcre and libgit2 (a dependent of pcre) have been
updated/modified
* Add example usage of meson_with_requirements macro
This commit adds mesa to the "examples" build.
This commit also changes the "examples" build to use the hermetic python
toolchain provided by rules_foreign_cc. As such, the python toolchain
built by rules_foreign_cc is no longer used, as it cannot be used in
workspace rules, .e.g pip_parse(). As such, the python2 build has been
removed from the examples as python2 is end-of-life.
Until Bazel 4.2.0, the built-in android toolchain required Python 2. As
such the minimum supported version has been upversioned to 4.2.0.
Note that the BAZEL_VC env var was removed from CI as mesa requires MSVC
2019.
* Set visibility for each target in foreign_cc_rule_variant
* Apply formatting changes
* Get meson examples working with bzlmod
Note that a newer version of pkgconfig than that installed in ubuntu 20
must be used to build libxau, therefore the built_pkgconfig_toolchain is
now registered
* Make cc_toolchain_utils.bzl more reusable
By using getattr, the helper functions in this file can be reused in
rules that do not define all of the framework attributes, e.g. bootstrap
rules.
* Bootstrap make reproducibly on Linux and macOS
Uses the Bazel C/C++ toolchain to bootstrap make and ensure that the
resulting binary contains no absolute and thus non-hermetic paths.
Building make reproducibly helps with remote caching and removes the
dependency on a C compiler installed on the host.
* Don't use deprecated targets for the preinstalled toolchains
* Add option to the repository macro for using built version of the build tools.
* Fix buildifier complaint
* Create BUILD_TMP directory when building make
* Corrections to toolchain setup for make_tool, cmake_tool and ninja_tool
* Fix path to built tools
* Attempting to fix make_tool for RBE
* Disable dependency tracking for make build
* Add cc_toolchain deps
* Add a built_toolchains.bzl file to be able to select the version to build
* Address buildifier issues
* Use geolocated mirror redirect for downloading make srcs
* Update docs
