Does anyone had any success with HDF5 ?

[nestor013]

Hi I'm trying to add HDF5 using cpm.make without success.
It basically won't compiler, although detection seems to run.
I followed some of the examples, which run fine. What am I doing wrong ?

For the record, I'm far from being a pro with CMake, so, please, be forgiving :-)
Any help would be appreciated. Thanks.

Here is the CMakeLists.txt I ended with:

cmake_minimum_required(VERSION 3.28)
project(MyApp LANGUAGES CXX C)

# Standards
set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

# set-up cpm.cmake
set(CPM_SOURCE_CACHE ~/.cache/cpm/)
set(CPM_DOWNLOAD_VERSION 0.40.8)
set(CPM_HASH_SUM "78ba32abdf798bc616bab7c73aac32a17bbd7b06ad9e26a6add69de8f3ae4791")
include(${CMAKE_CURRENT_SOURCE_DIR}/../cmake/get_cpm.cmake)

# Try to add hdf5
CPMAddPackage(

)

# Check if HDF5 was successfully added
if(NOT hdf5_ADDED)
  message(FATAL_ERROR "Failed to add HDF5 to the project")
endif()  

# Otherwise "Error: The dependency target "hdf5" of target "my_app" does not exist."
add_library(hdf5 INTERFACE IMPORTED)

# Otherwise missing headers
target_include_directories(hdf5 INTERFACE
  "${hdf5_BINARY_DIR}/src"
  "${hdf5_SOURCE_DIR}/src"
  "${hdf5_SOURCE_DIR}/src/H5FDsubfiling"
  "${hdf5_SOURCE_DIR}/c++/src")

add_executable(my_app src/main.cpp)

target_link_libraries(my_app PRIVATE
  hdf5
  z
)

add_dependencies(my_app hdf5)
