[Debian-med-packaging] Bug#1110434: libnifti2-dev: The NIFTI::znz target is misconfigured.

Package: libnifti2-dev
Version: 3.0.1-9.1+b1
Severity: important

Dear Maintainer,

I was packaging ROCm Performance Primitives (RPP) for Debian, which requires libnifti2-dev for complete
building of the test suite.

The file `/usr/share/cmake/NIFTI/NIFTITargets.cmake` incorrectly refers to `/usr/lib/libznz.so.3.0.0`,
which does not exist on multiarch systems like amd64. The correct path is likely:

    /usr/lib/x86_64-linux-gnu/libznz.so.3.0.0

The configuration fails with:

    -- rpp-test: Using RPP Backend: HIP
    CMake Error at /usr/share/cmake/NIFTI/NIFTITargets.cmake:129 (message):
      The imported target "NIFTI::znz" references the file
    
         "/usr/lib/libznz.so.3.0.0"
    
      but this file does not exist. Possible reasons include:
    
      * The file was deleted, renamed, or moved to another location.
    
      * An install or uninstall procedure did not complete successfully.
    
      * The installation package was faulty and contained
    
         "/usr/share/cmake/NIFTI/NIFTITargets.cmake"
    
      but not all the files it references.
    
    Call Stack (most recent call first):
      /usr/share/cmake/NIFTI/NIFTIConfig.cmake:1 (include)
      utilities/test_suite/CMakeLists.txt:118 (find_package)


    -- Configuring incomplete, errors occurred!

As a result, any downstream project that uses `find_package(NIFTI REQUIRED)` will fail during CMake
configuration.

To reproduce:

    git clone https://salsa.debian.org/rocm-team/rpp.git
    cd rpp

    # add dependency libnifti2-dev in d/control
    uscan --verbose --force-download --download-current-version
    debuild -us -uc
