Hi,

This is not an issue as your CMake perfectly works.

I'm integrating a new signature algorithm into OpenSSL. I already did it for OpenSSL 1.1.1 using the openssl-cmake project of janbar. However, his project doesn't support OpenSSL 3 and I need to move to this version.

I thought I could use yours, but as it pulls the OpenSSL code from the original openssl git it produces a Visual Studio solution that doesn't allow editing the code!

I pulled the code of OpenSSL from the official git. Is there a way to integrate your CMake with the local code to create a Visual Studio solution where the code of OpenSSL can be edited?

Thanks for your help.

Thx

In order to compile object files adapted to older macos versions, the CMAKE_OSX_DEPLOYMENT_TARGET option is generally add to the CMakeLists.txt as below,

if(APPLE)
    set(CMAKE_OSX_DEPLOYMENT_TARGET "11.0")
endif()

But this only works in CMake projects. As the openssl uses the ./configure file, the -mmacosx-version-min flag is not actually passed to the ./configure command. I've tried to add the following part to openssl-cmake/CMakeLists.txt, and it works,

diff --git a/CMakeLists.txt b/CMakeLists.txt

I wonder if there is any more suitable implements could help supporting the CMAKE_OSX_DEPLOYMENT_TARGET option.
