That comment was meant to convey that I have no idea.

Here are some commits in the packages feed that relate to ccache and cmake:

https://github.com/openwrt/packages/commit/7a01a09fe70dec20ea439ed3639e327a03e54d68

https://github.com/openwrt/packages/blob/master/utils/sumo/patches/010-ccache.patch

The easiest way to fix would probably be to override
CMAKE_HOST_C_COMPILER with $(HOSTCC_NOCACHE)
