The following imported targets are referenced, but are missing: absl::any_invocable while trying to use gRPC for a project

What version of gRPC and what language are you using?

I am using the latest version as of the 10th of September, 2023. I am using gRPC for C++ on linux.

PACKAGE VERSION 1.59.0-dev
CORE VERSION 35.0.0

I am trying to set up the code base of a project from Github. The code base uses gRPC and cmake to establish the dependencies.

From the CMakeLists.txt:

find_package(gRPC CONFIG REQUIRED)
message(STATUS "Using gRPC ${gRPC_VERSION}")

I think that I have successfully installed gRPC and its required dependencies. At least, while building gRPC from its source and then trying to install it (used cmake to make and install the packages) did not find any issues or errors.

$ git clone https://github.com/grpc/grpc/
$ cd grpc
$ git submodule update --init --recursive
$ cd cmake
$ mkdir build
$ cd build
$ cmake ../..
$ make -j`nproc`
$ sudo make install

But while trying to build the project which I am trying to setup (the corresponding CMakeLists.txt file), I get the following error:

Call Stack (most recent call first):
   /usr/share/cmake-3.25/Modules/ExternalProject.cmake:4185 (_ep_add_download_command)
   worker/CMakeLists.txt:17 (ExternalProject_Add)
 This warning is for project developers.  Use -Wno-dev to suppress it.
 Using protobuf 24.2.0
 CMake Error at worker/serverless_gpu/CMakeLists.txt:16 (find_package):
   Found package configuration file:

     /usr/local/lib/cmake/grpc/gRPCConfig.cmake

   but it set gRPC_FOUND to FALSE so package "gRPC" is considered to be NOT
   FOUND.  Reason given by package:

   The following imported targets are referenced, but are missing:
   absl::any_invocable

The contents of the file /usr/local/lib/cmake/grpc/gRPCConfig.cmake

# Module path
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_LIST_DIR}/modules)

# Depend packages




if(NOT TARGET absl::strings)
  find_package(absl CONFIG)
endif()


# Targets
include(${CMAKE_CURRENT_LIST_DIR}/gRPCTargets.cmake)
if(NOT CMAKE_CROSSCOMPILING)
  include(${CMAKE_CURRENT_LIST_DIR}/gRPCPluginTargets.cmake)
endif()

I am new to building systems that too using cmake. I am not very experienced. Can anyone please guide me to fix this issue?

I am using Ubuntu 18.04 with 5.4.0-150-generic kernel.

@drfloob @carlocab, Please can you help me with this issue? I don't know whether it is a bug or a problem from my end in the setup or some missing configuration (like some missing statements) in the code base I am looking into.

I am not that experienced enough to figure out the issue myself. Like where things are going wrong.

A good place to start would be the helloworld CMake example. If you want to build and install a self-contained gRPC library to a system folder, https://github.com/grpc/grpc/blob/ed310023cd128ec0cbd4f02e639fc909edaaadd0/examples/cpp/helloworld/cmake_externalproject/CMakeLists.txt
