* 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
This change updates the definitions of cmake toolchains to expose CMAKE
environment variable that makes it easier to integrate the toolchain
with other build rules (e.g., with rules_rust).
The macros utilise bazel "transitions" to set the `make` toolchain used
in the configure_make(), cmake() or make() rules to
a given make variant toolchain, e.g. preinstalled_nmake.
Note that the msvc constraint was removed from the
`exec_compatible_with` attribute of `preinstalled_nmake_toolchain` as
the condition is not actually met even when building with msvc. See
https://github.com/bazelbuild/bazel/issues/7730.
This will be tested in PR#729
