[PATCH 2/6] cmake: clean up variables shared between .bb and .inc

[Ross Burton]

Use EXTRA_OECMAKE in the non-cmake-inheriting cmake-native recipe, so
that the cmake.inc can assign once.

[PATCH 4/6] cmake: use system libuv

We have a recipe for libuv in oe-core, so use it in the target recipe to
avoid vendoring in more code.

Hi Ross,

Thanks for your patch.

This is failing while building nativesdk-cmake:

ERROR: Nothing PROVIDES 'nativesdk-libuv' (but virtual:nativesdk:/srv/pokybuild/yocto-worker/genericx86-64/build/layers/openembedded-core/meta/recipes-devtools/cmake/cmake_4.2.3.bb DEPENDS on or otherwise requires it). Close matches:
  nativesdk-libva
  nativesdk-libxau
  nativesdk-zlib
NOTE: Runtime target 'nativesdk-cmake' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['nativesdk-cmake', 'nativesdk-libuv']

https://autobuilder.yoctoproject.org/valkyrie/#/builders/4/builds/3188

Missing 'BBCLASSEXTEND = "nativesdk"' in libuv recipe?

Thanks,
Mathieu

[PATCH 6/6] cmake: remove obsolete patches

[Ross Burton]

0001-Disable-use-of-ext2fs-ext2_fs.h-by-cmake-s-internal.patch can be
replaced with two variable assignments to seed the results we want.

0002-CMakeLists.txt-disable-USE_NGHTTP2.patch is not needed anymore as
the vendored curl will disable the use of nghttp2 automatically if it
isn't found.
