Describe the bug
After git clone the resposity, I went to the Cachelib directory and execute the statement: ./ntrib/build.sh -d -j -v. It ended with an error.

-- Configuring done
CMake Error at allocator/CMakeLists.txt:26 (add_library):
  Cannot find source file:

Another Problem
What should I do to fix it，There really is no CacheAllocator.cpp in the allocator directory.
Moreover, when I run the statement : ./contrib/build.sh -j -T , it showed another problem:

make[2]: *** [CMakeFiles/logging_unittest.dir/build.make:102: logging_unittest] Error 1
make[1]: *** [CMakeFiles/Makefile2:879: CMakeFiles/logging_unittest.dir/all] Error 2
make: *** [Makefile:166: all] Error 2
build-package.sh: error: make failed
build.sh: error: failed to build dependency 'googlelog'

It seems that after commit dfe99bdfe7bd17d444d268b4364382900d01dc8f, CacheAllocator.cpp was split into multiple files (as it can be read here).

However, the cachelib/allocator/CMakeLists.txt was not updated accordingly.

I had to use fbthrift commit aa448e447ebab229e8d4ebb5fa30f1a0c522d487 and fmt tag 11.0.2 once I applied this patch to get a build.

Also I made these changes after the compressedptr update:
