Andreas Ziegler 6ab8b1e263 meson-package: prevent cmake find_package() picking up host libraries
The meson build system uses (1) pkg-config and (2) cmake find_package to locate
dependencies and stops only if a package is found. Cmake uses a toolchain file
that is generated by meson from the existing configuration [1].

The cmake toolchain file misses CMAKE_FIND_ROOT_PATH and CMAKE_FIND_ROOT_PATH_*
settings, and find_package() falls back to the default behaviour and looks for
dependencies on the build machine (the Buildroot HOST_DIR).

Use a feature introduced in meson 0.56.0 [2] to pass the Buildroot toolchain
file to cmake instead of using a meson-generated one.

Fixes the following build failures:
