Is there someone able to find abseil libraries in protobuf25.2 ?

Any help is valid

here is the procedure.

git clone --recursive https://github.com/protocolbuffers/protobuf.git protobuf-25.4

cd protobuf-25.4

cmake -Dprotobuf_BUILD_TESTS=OFF -DABSL_BUILD_TESTING=OFF -DABSL_USE_GOOGLETEST_HEAD=OFF -DABSL_PROPAGATE_CXX_STD=ON -DCMAKE_CXX_STANDARD=17 .
cmake --build . --parallel 10
sudo cmake --install .

sample.proto

syntax = "proto3";

message MyMessage {
int32 id = 1;
string name = 2;
}

protoc -I=. --cpp_out=. sample.proto

main.cpp

#include "sample.pb.h"
#include <iostream>

int main() {
MyMessage message;
message.set_id(123);
message.set_name("Hello, Protobuf!");

std::cout << "ID: " << message.id() << ", Name: " << message.name() << std::endl;

return 0;
}

g++ -std=c++17 -o abseil_test abseil_test.cpp -I/usr/local/include/absl -L/usr/local/lib -labsl_strings -labsl_time -labsl_flags -labsl_raw_logging_internal -labsl_cord -labsl_log_internal_message -labsl_log_internal_check_op

I suspect that invoking pkg-config --cflags --libs protobuf (or similar) might be necessary in order to specify all of the dependencies correctly.
