Hello everyone!

I am trying to add an external project to ParaView Superbuild and I am having some difficulty due to the project layout. I have created a project file `projects/unix/<name>.cmake` and added the project to `versions.cmake`.

The project has a makefile that is located within a “src” subdirectory of the project, i.e. it gets extracted to `superbuild/<name>/src/src/Makefile`. The project does not support out of source builds.

How can I add a project to paraview superbuild using the superbuild\_add\_project command so that it will work with this my project layout? Is there a way to set the working/build directory to `superbuild/<name>/src/src`? Or is there a way to do `cd src` before running `make` in the BUILD\_COMMAND?

Thanks everyone! 🙂

Add `BUILD_IN_SOURCE 1` to the arguments for the project command.

Thanks for your reply 🙂

I had tried adding `BUILD_IN_SOURCE 1` but the problem I had was that the `make` command is run in `superbuild/<name>/src` and I need it to run in a src subdirectory, i.e. `superbuild/<name>/src/src`.

Can I use `BUILD_IN_SOURCE 1` then somehow move to a subdirectory before running the build command?

There is `SOURCE_SUBDIR <subdir>` for treating the top-level source directory as a subdirectory of the normal one.

The superbuild is basically a layer on top of [`ExternalProject`](https://cmake.org/cmake/help/latest/module/ExternalProject.html) which does some enable/disable toggling and add support for `PROCESS_ENVIRONMENT`, so anything mentioned in those docs are supported in the superbuild as well. The superbuild currently carries 3.9’s `ExternalProject` module, but uses the one with your CMake if it is at least 3.9.

I tried adding `SOURCE_SUBDIR src` to my `superbuild_add_project` command, but my build command seems to run in the same directory as before. Perhaps the `SOURCE_SUBDIR` option only works with CMake projects and not Makefile projects?

Thank you 🙂

Hmm, that would indeed seem to be the case. I’ll look at making an MR for CMake that we can put into the superbuild.

I’ve made an issue for bringing it into the common-superbuild: [https://gitlab.kitware.com/paraview/common-superbuild/issues/46](https://gitlab.kitware.com/paraview/common-superbuild/issues/46)
