adios2-config installation failure

We ask the community to always report bugs. Please open a new issue if some other comes up in the conversation. It will help us stay on topic and manage tasks more efficiently.

Describe the bug After the compilation and main installation have finished, it fails on the last steps:

-- Installing: ./pkg/adios2/usr/lib/cmake/adios2/adios2-config.cmake
/tmp/tmp.WQe96LCPvH ~/aur/__rebuilds/adios2/src/build

CMake Error at CMakeLists.txt:9 (find_package):
  By not providing "Findadios2.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "adios2", but
  CMake did not find one.

  Could not find a package configuration file provided by "adios2" with any
  of the following names:

    adios2Config.cmake
    adios2-config.cmake

  Add the installation prefix of "adios2" to CMAKE_PREFIX_PATH or set
  "adios2_DIR" to a directory containing one of the above files.  If "adios2"
  provides a separate development package or SDK, be sure it has been
  installed.

To Reproduce

  cmake -B build -S ${pkgname^^}-${pkgver} \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DCMAKE_SKIP_RPATH=ON \
    -DADIOS2_USE_EXTERNAL_DEPENDENCIES=ON \
    -DADIOS2_HAVE_HDF5_VOL=OFF \
    -DADIOS2_BUILD_EXAMPLES=OFF #\
    #-DMGARD_INCLUDE_DIR=/usr/include/mgard
    #-DADIOS2_HAVE_HDF5_VOL needs hdf5-openmpi
  make VERBOSE=1 -C build

make -C build DESTDIR="${pkgdir}" install

Expected behavior adios2-config dummy CMake project should not make any problems

Desktop (please complete the following information):

• OS/Platform: ArchLinux
• Build: gcc 13.1.1, cmake 3.26.4

Which ADIOS2 version are you using?

[meerfrau]

current git master

[vicentebolea]

related #3473

@meerfrau we want to get rid of this adios2-config shell script soon. In the meanwhile you can disable the generation of it and its testing (which fails here) with: -DADIOS2_INSTALL_GENERATE_CONFIG=OFF

[meerfrau]

@vicentebolea This would indeed work!

[vicentebolea]

This might have been resolved at #3760
