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:

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
