I fixed it locally, but I have another issue when building libdatachannel, without specifying the library status, cmake should build a static or shared library depending on BUILD_SHARED_LIBS. In my case, BUILD_SHARED_LIBS is set to ON but libdatachannel is built statically nonetheless.

Nvm, I found it.

[Nemirtingas]

Everything should be ok now.

For port libdatachannel and libjuice all features are tested successfully in the following triplet:

• x86-windows
• x64-windows
• x64-windows-static

[Nemirtingas]

For port libdatachannel and libjuice all features are tested successfully in the following triplet:

* x86-windows

* x64-windows

* x64-windows-static

I just tested

• x86-linux
• x64-linux
• x86-linux-dynamic
• x64-linux-dynamic
  It compiles just fine.
