When I compiled the SlicerHeart again using CMake. I just want a Release version.  
The `OPENSLL_INCLUDE_DIR` was set to `C:/Slicer/SlicerBuild/OpenSSL-install/Release/include`  
But when compiling, there is error:

```auto
8>CMake Error at C:/Slicer/SlicerBuild/Slicer-build/SlicerConfig.cmake:704 (message):
8> Variable OPENSSL_INCLUDE_DIR defined prior calling 'find_package(Slicer)'

8> CMakeLists.txt:21 (find_package)

```

Maybe the `OPENSSL_INCLUDE_DIR=C:/Slicer/SlicerBuild/OpenSSL-install/Debug/include` is set automatically ??

Anyone who occurred this ?

thanks

Hello @whu. I can try to reproduce this on Linux. I’ll try 3D Slicer `master` branch and SlicerHeart `master` branch. Please, let me know if you have used any other version/commit of any of those.

Rafael.

@whu, I’ve tried the latest Slicer (`master` branch) with the latest SlicerHeart (`master` branch) and I cannot reproduce this problem (Linux, though). From your last reply, it is not clear whether you are using the `master` branch for both Slicer and SlicerHeart. Could you give it a try and let us know if there are still problems?

@whu Could you make sure you are configuring both Slicer and SlicerHeart specifying the same configuration (Debug, Release, …) ?

I used the debug mode under Windows using vs2019, successful.  
Later I changed to Release mode, then that compiling error happened.  
I am not sure that would be occured again.

If this was not a clean build, it likely explained the issue. Toggling between built type on windows is not tested or supported.
