I had a look at mbedtls cmake code.
It's definitely not really the usual way to use cmake.

They do not use cmake primitives to generate the config.h file [1] or
check for pthread [2]... :(
So, this forces us to either workaround this in buildroot's *.mk files
(like you did), or rework the mbedtls cmake code.
I submitted few patches to improve the situation (see PR [3]), and
hopefully get rid the hooks sooner or later.
