gRPC fails to find its own third-party source

Question

I'm trying to use cmake instead of bazel to build gRPC。 However, the following ERROR messages received:

 CMake Error at CMakeLists.txt:1055 (add_library):
   Cannot find source file:

     third_party/address_sorting/address_sorting.c

   Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm .h
   .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90 .f95 .f03 .hip .ispc

 CMake Error at CMakeLists.txt:3949 (add_library):
   Cannot find source file:

     third_party/upb/third_party/utf8_range/naive.c

   Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm .h
   .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90 .f95 .f03 .hip .ispc

 CMake Error at CMakeLists.txt:1055 (add_library):
   No SOURCES given to target: address_sorting

 CMake Error at CMakeLists.txt:3949 (add_library):
   No SOURCES given to target: upb

However, clearly, both files exist:

➜  grpc git:(master) ✗ ll third_party/upb/third_party/utf8_range/naive.c
-rwxrwxrwx 1 lvision lvision 3.9K Mar  8 13:34 third_party/upb/third_party/utf8_range/naive.c
➜  grpc git:(master) ✗ ll third_party/address_sorting/address_sorting.c
-rwxrwxrwx 1 lvision lvision 14K Mar  8 13:34 third_party/address_sorting/address_sorting.c

Any suggestions?

Sorry. Problem seems to be solved?? I actually build it out from source by

mkdir build
cd build

According to the official doc gRPC C++ - Building from source, this time, I tried

mkdir -p cmake/build
cd cmake/build

this seems to be okay... This doesn't seem to make sense. But, anyway, it's built now...
