Mixing non virtualenv packages with virtualenv packages about catkin_virtualenv

[paulbovbel]

@YXGuan, your problem is not related to this issue, please check ROS answers for basic support. You should be invoking find_package(... catkin_virtualenv) somewhere, and you're not.

[paulbovbel]

Looks like your CMake is leaking between packages - are you using catkin_make?

This is certainly something that can be fixed by creating a new macro rather than overriding catkin_install_python, which may have been a poor decision in retrospect.

An easier approach may be just to suggest you use a build tool that isolates package builds, i.e. https://catkin-tools.readthedocs.io/en/latest/

[paulbovbel]

Closing due to suggested workaround likely being effective.

Hi Paul @paulbovbel ,

I made the same mistake you mentioned above and it really backfires. Could you please elaborate on how to " create a new macro" please?

-- ==> add_subdirectory(nmea_navsat_driver)
-- Could NOT find catkin_virtualenv (missing: catkin_virtualenv_DIR)
-- Could not find the required component 'catkin_virtualenv'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.
CMake Error at /opt/ros/noetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "catkin_virtualenv"
  with any of the following names:

    catkin_virtualenvConfig.cmake
    catkin_virtualenv-config.cmake

  Add the installation prefix of "catkin_virtualenv" to CMAKE_PREFIX_PATH or
  set "catkin_virtualenv_DIR" to a directory containing one of the above
  files.  If "catkin_virtualenv" provides a separate development package or
  SDK, be sure it has been installed.

FYI, catkin_virtualenv is already installed on my local machine

Thank you in advance.

hi @paulbovbel i have met the same question with [DerNeuburger] . Can you describe more clearly about creating a new macro ?

This is pretty annoying, would be nice if the macro is not overwritten.
