Fix: Add GNUInstallDirs to resolve CMAKE_INSTALL_FULL_LIBDIR undefined error

[aayushyatiwari]

While building standalone SOFIE with -Dtesting=ON, cmake configuration
failed with the following error:

CMake Error at RootMacros.cmake:2257 (cmake_path):
cmake_path undefined variable for input path.

RootMacros.cmake uses CMAKE_INSTALL_FULL_LIBDIR internally in
ROOT_APPEND_LIBDIR_TO_INSTALL_RPATH, which is only defined by CMake's
GNUInstallDirs module. Since standalone SOFIE never included it, the
variable was undefined causing the error.

Fix: Added include(GNUInstallDirs) after include(${ROOT_USE_FILE})
in CMakeLists.txt.

Hi @aayushyatiwari
Thanks for your PR. One question, do you see these errors after you have sourced a pre-compiled binary of ROOT and the setup.sh file?

[aayushyatiwari]

Hi @sanjibansg, I encountered this error using ROOT built from source (v6.39.01 on the sofie-dev branch) rather than a pre-built binary. I haven't tested with a pre-built binary. The fix still applies since RootMacros.cmake uses CMAKE_INSTALL_FULL_LIBDIR regardless of how ROOT was built, i think. but I can verify with a pre-built binary if needed.

The source of the ROOT installation should not make a difference. Can you send the steps you performed to reproduce the error on our side?

[aayushyatiwari]

machine: Ubuntu 24.04
ROOT: v6.39.01 built from source.

Steps:

git clone https://github.com/sanjibansg/SOFIE.git
cd SOFIE
mkdir build && cd build
cmake -Dtesting=ON -DCMAKE_INSTALL_PREFIX=../install -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
cmake --build . --target install -j10

the exact error was this:

-- Could NOT find Python module torch. Corresponding tests will be disabled.

Could you try sourcing the installed ROOT libraries after you have built it?

source install/bin/thisroot.sh

[aayushyatiwari]

The error occurs during cmake configuration, before the build step. Sourcing ROOT's thisroot.sh was already done before running cmake.
Before the cmake, I had root built from root_src and doing root --version did

(torchgpu) _sofie\ $ root --version
ROOT Version: 6.39.01
Built for linuxx8664gcc on Mar 05 2026, 20:20:44
From heads/sofie-dev@41e48a99

Could you clarify which thisroot.sh you're referring to?

[aayushyatiwari]

For clearance, I had build root_src from official root build from source website.
I completed my excersises for improving parsers for pytorch and keras projects and so I was installing sofie standalone for the ML inference for heterogaenous architectures using SOFIE project when I figured I had already built root and sourced it from the root_src folder. So I just did the steps mentioned in this repo's readme.md file.

Does that clear the setup part a bit?
