cmocka only build a shared library libcmocka.so, so this package must not be
selected on static only build (it's hard coded in src/CMakeLists.txt):
depends on !BR2_STATIC_LIBS

And add a comment here:
comment "cmocka needs a toolchain w/ dynamic library"
depends on BR2_STATIC_LIBS
Also I tried to build with a uClibc-ng toolchain without stack protection
support (libssp) and cmocka fail to build. I haven't tested with a musl toolchain.

collect2: erreur: ld a retourné 1 code d'état d'exécution
-fstack-protector is added by cmake/Modules/DefineCompilerFlags.cmake:
check_c_compiler_flag_ssp("-fstack-protector" WITH_STACK_PROTECTOR)
if (WITH_STACK_PROTECTOR)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fstack-protector")
endif (WITH_STACK_PROTECTOR)
For some reason, -fstack-protector is still added even when the ssp support is
disabled in the toolchain. It build fine when -fstack-protector is removed.
Thoughts ?
Best regards,
