common: configure_cache_path: Use PROOT to avoid hardcoding absolute path

[NGenetzky]

Problem

In the CACHE_DIR variable below is an absolute path. Consider using ${PROOT} instead. This has the same result for the current builds but will have the added result of allowing the project to build even if it is moved to a new location.

bash ${PETALINUX_CONFIGS_FOLDER}/project/config.cache.sh $ARCH $CACHE_DIR

NOTE: that other parts of this function suffer from #25 .

Solution

You can fix this by changing the value passed to the other script.

bash "${PETALINUX_CONFIGS_FOLDER}/project/config.cache.sh" "$ARCH" "\${PROOT}/../cache"
