Could NOT find Protobuf (missing: Protobuf_PROTOC_EXECUTABLE)

Question

When I am doing a cmake in the build directory of the project I am getting this error. Initially I got a

protobuf-config.cmake not found

error. So I gave a path of the protobuf-config.cmake file to Protobuf_DIR. Later it started to show this new error:

CMake Error at /opt/cmake/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find Protobuf (missing: Protobuf_PROTOC_EXECUTABLE)

(found suitable version "3.6.1", minimum required is "3.0.0")

I am also attaching the error log file: https://drive.google.com/open?id=1y7BZ6lDBtxvla7r-o188xM_FjwLqwhCx

I am doing this on Ubuntu-18 with cmake version: 3.13 and protobuf version: 3.6.1

Answer 1

You probably don't have the Protobuf compiler and development files installed. To fix that, run this command:

sudo apt-get install protobuf-compiler libprotobuf-dev

Alternatively, if you're building Protobuf by hand, you can't build it with the build type as RelWithDebInfo because that causes issues with the library and CMake.
