# CMake toolchain file for Buildroot

# In order to allow the toolchain to be relocated, we calculate the
# HOST_DIR based on this file's location: $(HOST_DIR)/usr/share/buildroot
# and store it in RELOCATED_HOST_DIR.
# All the other variables that need to refer to HOST_DIR will use the
# RELOCATED_HOST_DIR variable.
