it seems that for some reason the usage requirement of C++17 is not propagated.

I think I found the bug.

This is how protobuf targets are defined by find_package(Protobuf CONFIG):

add_library(protobuf::libprotobuf-lite SHARED IMPORTED)

set_target_properties(protobuf::libprotobuf-lite PROPERTIES
  INTERFACE_COMPILE_DEFINITIONS "PROTOBUF_USE_DLLS"
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include"
  INTERFACE_LINK_LIBRARIES "abseil_dll"
)

# Create imported target protobuf::libprotobuf
add_library(protobuf::libprotobuf SHARED IMPORTED)

set_target_properties(protobuf::libprotobuf PROPERTIES
  INTERFACE_COMPILE_DEFINITIONS "PROTOBUF_USE_DLLS"
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include"
  INTERFACE_LINK_LIBRARIES "abseil_dll"
)

# Create imported target protobuf::libprotoc
add_library(protobuf::libprotoc SHARED IMPORTED)

set_target_properties(protobuf::libprotoc PROPERTIES
  INTERFACE_COMPILE_DEFINITIONS "PROTOBUF_USE_DLLS"
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include"
  INTERFACE_LINK_LIBRARIES "abseil_dll"
)

The INTERFACE_LINK_LIBRARIES is abseil_dll, but the imported target defined by find_package(absl REQUIRED) is absl::abseil_dll.

[traversaro]

Ok, I found the problem. The root cause of the problem is fixed by abseil/abseil-cpp#1466, but a temporary fix for protobuf is provided in protocolbuffers/protobuf#12978 .
