Hi, I test helloword itk project on Windows 10, MSYS2, but failed. Here is my code:
```auto
// main.cpp
#include "itkImage.h"
#include "itkImageFileWriter.h"
int main(int argc, char *argv[]) {
std::cout << "ITK Hello World !" << std::endl;
return EXIT_SUCCESS;
}
```
and my `CMakeLists.txt`：
```auto
# CMakeLists.txt
project (hello)
add_executable(hello)
find_package(ITK REQUIRED)
include(${ITK_USE_FILE})
target_sources(hello PRIVATE main.cpp)
target_include_directories(hello PRIVATE ${ITK_INCLUDE_DIRS})
target_link_libraries(hello ${ITK_LIBRARIES})
```
`cmake -B build` outputs:
```auto

itk 5.0.1 build with this [PKGBUILD](https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-itk/PKGBUILD).

Hi @hubutui,
Please try the ITK Git `v5.1.0` tag, which has addressed MinGW-w64 MSYS issues (although I have not tested that `PKGBUILD` recipe).
Thanks,
Matt

This may need to be `OFF`, but make sure to use `v5.1.0`.

OK, I’ll try to create itk 5.1.0 from the `PKGBUILD` recipe with `ITK_USE_SYSTEM_HDF5=OFF`. I’m not sure how long would it take to build it.

The build will be much faster with the _Ninja_ generator. It should take \< 10 minutes.

Wow, could this be done with AMD Ryzen R5 3550, 16G RAM? I can’t believe it.

Yes, with that system, the build will be very fast 🏍

I have build itk 5.1.0 with `ITK_USE_SYSTEM_HDF5=ON`. And now this project could be built, but fail to run. Error log:
```auto
D:/Projects/hello/build-system-hdf5/hello.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
```
It did not show me which lib is missing.
I also try `ITK_USE_SYSTEM_HDF5=OFF`, there is a file conflict (`/mingw64/lib/libhdf5.settings`) with hdf5 from the system. I manual remove it from the final itk pkg to avoid file conflict. I could build this helloworld project, but could not run it, with same error.

The build a _hello world_ without worrying about determining the dependent libraries and setting up the run time environment to find them, build ITK independently from the MSYS package with its default build configuration. It will build ITK and third party static libraries that get embedded into the executable.

So you mean if I build `itk` with `ITK_USE_SYSTEM_HDF5=OFF`, then `itk` will build `hdf5` and statically link to it. Then maybe `itk` should not install `/mingw64/lib/libhdf5.settings` to the system, right?

Yes.
The steps, essentially:
```auto
# Open an MSYS shell
git clone https://github.com/InsightSoftwareConsortum/ITK
cd ITK
git checkout v5.1.0
cd ..
mkdir ITK-build
cd ITK-build
cmake -GNinja -DBUILD_TESTING=OFF ../ITK
ninja
cd ..
cd hello-world-build
cmake -DITK_DIR=$PWD/../ITK-build -GNinja ../hello-world
ninja
```
> Then maybe itk should not install /mingw64/lib/libhdf5.settings to the system, right?
Yes, this should not be the case if `ITK_USE_SYSTEM_HDF5` is `OFF`.

Hmm, but in fact, `make install` will install `libhdf5.settings` as `/mingw64/lib/libhdf5.settings`.

I think you should add #include\
