The use of CACHE in the SNMALLOC_STATIC_LIBRARY_PREFIX was not correctly handled by cmake before 3.21. > The “set(CACHE)” command no longer removes a normal variable of the same name, if any. See policy “CMP0126”. Changing the minimum version means that containing projects can do: ```CMake set(SNMALLOC_STATIC_LIBRARY_PREFIX "my_prefix") ``` Without this, there were weird behaviours that the first compile used "sn_" and then subsequent compiles used "my_prefix". Thanks to @achamayou for debugging this in CCF. microsoft/CCF#7161
