[CMake] FindHDF5 works on Linux, fails on Windows

[Ohs Nicholas]

Hello,

When I use FindHDF5 to setup my project it works perfect on Arch-Linux to produce make scripts. However, when I generate Visual Studio 2015 64bit solutions, I get an error during compile, as Visual Studio is trying to link against hdf5_cpp.dll directly throwing a LNK1107 error. Instead of linking directly against the *.dll I think on windows it should link against the corresponding *.lib. Is this a bug in FindHDF5? Can anybody reproduce the issue?

Info about the System:

-          Windows 10 64bit

-          Visual Studio 2015 64bit project

-          CMake 3.7.0

-          HDF5 1.10.0

Here what I do:
Create build folder, call: "cmake -G "Visual Studio 14 2105 Win64" .."

With part of the output being
                "Found HDF5: C:/Program Files/HDF_Group/HDF5/1.10.0/bin/hdf5_cpp.dll (found version "1.10.0") found components:  CXX"

Here is the CMakeLists.txt

cmake_minimum_required(VERSION 3.6 FATAL_ERROR)
project("justTesting")
find_package(HDF5 COMPONENTS CXX REQUIRED)
                include_directories(${HDF5_INCLUDE_DIRS})
add_executable(hdf5_test test.cpp)
target_link_libraries(hdf5_test ${HDF5_CXX_LIBRARIES})

and here the test.cpp

#define H5_BUILT_AS_DYNAMIC_LIB
#include <H5Cpp.h>

int main()
{
                H5::H5File file = H5::H5File("test.h5", H5F_ACC_EXCL);
                file.close();
}

Then I open the solution, click on ALL_BUILD and build it. The output is in short:

                LNK1107 Invalid or corrupt file: cannot read at 0x380, File: hdf5_cpp.dll

The entire log:

========== Build: 2 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

So my question again from above:

-          Can anybody reproduce the issue?

-          Is this a bug in FindHDF5?

Cheers
Nicholas
