error: use of undeclared identifier 'absl'

Following the installation I have the problem with absl :

Any ideas how to solve this ?

See my comment in the other thread! I think that the fix will help you!

If you are using the library as an external project in CMake, here is how I integrated it:

ExternalProject_Add(protobuf 
  SOURCE_DIR "${CMAKE_SOURCE_DIR}/libprotobuf-mutator" 
  INSTALL_DIR ${CMAKE_BINARY_DIR} 
  CMAKE_ARGS "-DCMAKE_INSTALL_PREFIX=${PROTOBUF_INSTALL_PREFIX}"
  CMAKE_CACHE_ARGS "-DLIB_PROTO_MUTATOR_DOWNLOAD_PROTOBUF:STRING=On")
