CMake Error at CMake/vtkModuleMacros.cmake:950 (find_package):
  By not providing "FindZFP.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ZFP", but
  CMake did not find one.

  Could not find a package configuration file provided by "ZFP" with any of
  the following names:

    ZFPConfig.cmake
    zfp-config.cmake

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

I believe the Pyexpander problem is not a fatal error.

Any suggestions?

vtk-8.1.0-r2 and USE=all-modules fails with the same error.

What about 8.2.0?

it still want zfp for me

    sci-libs/vtk: improve all-modules USE flag
    
    - add missing flags to REQUIRED_USE
    - add new mysql USE flag - needed by all-modules, adds new dependency on
            dev-db/mysql-connector-c. Dev-db/mariadb-connector-c isn't supported
            by this version. Fix an issue with using of deprecated my_bool when
            using mysql-connector-c.
    - remove xdmf2 USE flag, block sci-libs/xdmf2 with all-modules:
            sci-libs/xdmf2 doesn't ship any cmake configuration files, which leads
            to configuration errors when trying to build against external xdmf2
    - block sci-libs/xdmf2: when built against internal xdmf2, there are header
            file collisions with the header files installed by sci-libs/xdmf2
    - add dependency on sci-libs/kissfft, bug #754684) and drop bundled
    - fix an issue with xdmf3 library being installed in both library locations,
            lib and lib64
    - fix QA issues with RPATH
    - byte compile python files
    - disable searching for zfp (no package in tree)
    - addresses some QA issues with defined but unused cmake variables: fixing all
            of them would need a thorough testing of each single USE flag and checking
            where these belong to, in this over-complex build system (bug #660582)

I disagree in closing this for vtk-8, I've packaged zfp and vtk-8 should depend on it (with vtk-9 things are complicated)

Just my 2 cents.

- The specific issue at hand has been solved with the PR and thus the bug has to be closed. As always, there are numerous ways to solve a problem. The chosen one may not be the optimal solution, but that's IMO not important in that case. The ebuild can be improved any time later.
- Adding a new ebuild to ::gentoo takes time, usually a lot of time. From a few weeks up to many many months, anything is possible. Do you think, it's a good idea to wait, say, another year for this bug to be solved, if there's an easy way to get a quick fix and later improve on it, once the dependency has been added to the tree?
- Why didn't you comment on the PR about this? It would have been easy to change the closed tag into a bug tag, if desired. IMO that would have been the proper place to discuss about it, in time and with the possibility to adjust.
- This bug has been open for more than 3 years by now. Enough time to step up on it and propose a solution for yourself. Why haven't you done this? I didn't grab on the maintainership of the package (see the resolved comments about it in metadata.xml on my vtk-9 PR). I'm maintaining an ebuild for vtk for years in my overlay, trying to improve on it and fix issues and know this beast is not only fun, and get's you frustated easily. It's over-complex build system is a challenge to fully understand and at first I didn't want to be a named maintainer for the package. You are more than welcome to add yourself as a maintainer and take care of it, so you can solve things in a better way.
- TBH, I get a feeling you just wanted to start a fight with your comment, because it hasn't been solved the way *you* wanted it to be done.
