I'm testing this with the other package. I could be very wrong but it
seems that ccache is just broken with cmake. My current implementation
is a variable CMAKE_NOCCACHE that disable the use of ccache for that
package. For now I found that this is needed for both the host build and the
pkg build. (libubox, opkg, libjson-c affected) Can you check if you can
compile that package with not problem with your implementation. Just
to make sure I'm not making things wrong.
