HDF5 Build with Shared Libraries in MSYS2 Causing CMake Errors

[ahnaf-tahmid-chowdhury]

Description

I successfully built and installed HDF5 from source with shared libraries enabled. However, when I attempt to use HDF5 in another CMake project and call find_package(HDF5), CMake fails with errors related to missing IMPORTED_LOCATION or IMPORTED_IMPLIB properties for hdf5-shared and hdf5_hl-shared.

Error Output

Expected Behavior

The find_package(HDF5) command should locate the installed HDF5 shared libraries, set up imported targets, and provide the necessary include directories and library paths.

Environment

• Operating System: Windows (MSYS2/CLANG64/MINGW64)
• HDF5 Version: 2.0.0 (built from source)
• CMake Version: 3.31.2
• Compiler: Clang/GCC
• Build Type: Shared Libraries (-DBUILD_SHARED_LIBS=ON)

The HDF5 that is supposed to be found - was it built with CMake (has hd5-config*.cmake files in CMake folder) or not.
Did you provide a HDF5_ROOT ENV var location?

[ahnaf-tahmid-chowdhury]

Yes, and it works when I set HDF5_NO_FIND_PACKAGE_CONFIG_FILE=ON. So, I think hd5-config*.cmake is unable to set the targets properly.

Strange that a CMake built install only works with MODULE find and not CONFIG version.
If you could provide a few more details about the HDF5 specific parts of the build command:
HDF5_ROOT is set to the root location and not the CMake subdir.
OR add message (STATUS ...) lines in the hdf5-config file to trace execution and settings?

[ahnaf-tahmid-chowdhury]

Here is the workflow file where I've used HDF5:
windows_build_test.yml.

We have one that builds but not one that tests the install.

WOW - there is a lot going on with CMake - HDF5- libaec and find_package!

First, a good to know CMake option is -DCMAKE_FIND_DEBUG_MODE:BOOL=ON which shows the process and files that CMake used to get the package info.

Setting ENV{SZIP_ROOT} is all that is needed to find the package. (HDF5 does require -DSZIP_USE_EXTERNAL:BOOL=OFF and -DHDF5_ALLOW_EXTERNAL_SUPPORT:STRING="NO")

The next problem is that libaec doesn't set SZIP_LIBRARIES just SZIP_LIBRARY and libaec_LIBRARY.

I am running into some other issues outside of the find_package.

See #5182 for SZIP/libaec fixes against develop

Just a note that the CMake provided FindHDF5.cmake module expects an autotools built HDF5, to find a CMake built HDF5 use find_package with the CONFIG option.
