[CMake] [EXTERNAL]: FindProtobuf in specified dirs

Tue Oct 25 09:35:49 EDT 2016

This is a shot in the dark, but if I remember correctly, building CMake requires a separate version of CMake in order to bootstrap itself. So when you run ccmake (or cmake-gui) to configure the new version of CMake you’re trying to build, there might be some Boolean option in there that will disable doc generation completely.

Actually, I'm trying to compile cmake 3.0.2 now.

I did exactly that for protobuffers, and it compiled file. It's just the package config file that still requires 2.8.12 and I'm not sure of the consequences of changing that. So I'm trying to build 3.0.2 on squeeze now, and having a hard time building the docs because of sphinx. If I could skip the docs, that would be fantastic.

Thanks,
Homero

I actually haven’t ever tried to build protobuffers myself, so I can’t comment on its doc generation or sphinx dependency. Sorry if this seems obvious, but have you tried modifying protobuffer’s CMakeLists.txt file so that it uses the same 2.8.9 CMake you are using? 2.8.12 may not be that far off from 2.8.9; it just might be the version of CMake they happened to download at the time, rather than a hard requirement on it.

Thanks for your help.

I was able to download and compile protobuffers 2.7 using cmake, however the cmake config for protobuffers is fixed for 2.8.12, while I need it to work with cmake 2.8.9 as it's going to run in system frozen in Debian Squeeze (Squeeze actually defaults on cmake 2.8.2 and I got it to install 2.8.9 from Wheezy).

Currently I'm trying to create a debian package from cmake 3.0.2 on squeeze, but I'm having a hard time due to dependencies on sphinx. Do you have any ideas on how to circumvent the doc generation?

Thanks and regards,
Homero.

I believe the protobuf-config.cmake.in<http://protobuf-config.cmake.in> generates a protobuf-config.cmake file once you actually use CMake to build protobuf itself.

Hello,

I'm working on enhancing the build process in my company by using CMake, and I'm having trouble to have it find the Google Protocol Buffers binary and libraries in a specific directory in my workspace.

Due to several reasons, we cannot install protobuffers directly in our environment, so I have it download and unpack a zip file with the protobuffer library and header files in a directory in my home folder. However, when I use the find_package directive giving said folder as a hint it complains that it could not find a protobuf-config.cmake file and fails. I couldn't find any such file anywhere, the only thing coming close is a "protobuf-config.cmake.in<http://protobuf-config.cmake.in>" in the protobuf source tree and I don't know if I can use that.

Do I have to provide my own protobuf-config.cmake file, or I'm using it completely wrong?

We are frozen in protocol buffers 2.4.1. I guess we can upgrade to 2.7.0, but we can't use 3.0.x.

Thanks,
Homero.
