ROSEnv

The ROSEnv generator is an environment generator that, in conjuction with CMakeDeps and CMakeToolchain, allows to consume Conan packages from a ROS package.

conanfile.txt

  1. [requires]
  2. fmt/11.0.2
  4. [generators]
  5. CMakeDeps
  6. CMakeToolchain
  7. ROSEnv

This generator will create a conanrosenv.sh script with the required environment variables that allow CMake and Colcon to locate the pacckages installed by Conan.

This script needs to be sourced before the colcon build command:

  1. $ cd workspace
  2. $ conan install ...
  3. $ source conanrosenv.sh
  4. $ colcon build
