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: http://autobuild.buildroot.org/results/056/05673ed04c6f044f1b56b9d5342d61653be43a18/ http://autobuild.buildroot.org/results/f0a/f0a9e719114f19dc9d20622ed85dd4f8e968c20f/ http://autobuild.buildroot.org/results/527/527ee199813abbacd61c3fa32b517ea60af60659/ [1[ see mesonbuild/cmake/toolchain.py [2] see https://mesonbuild.com/CMake-module.html#cross-compilation Signed-off-by: Andreas Ziegler <br015@umbiko.net> Signed-off-by: Yann E.
