とあるBSP(yocto)でsdkを構築し、サンプルソフト(helloworld)をクロスコンパイルしようとしたところ、CMakeエラーが出ました。
・HostPCの再起動
・/opt/poky/2.5.2/の削除と再度shの実行
・helloworldのbuildフォルダ削除
を繰り返しましたが、改善されませんでした。
本件に関して、何か知見がございましたらご教授いただけないでしょうか？

■構築手順
local.confにSDKMACHINE ?= "x86_64"を追記
bitbake core-image-weston-sdk -c populate_sdk
sh ./poky-glibc-x86_64-core-image-weston-sdk-aarch64-toolchain-*.sh
HostPC再起動
