When trying to generate an Xcode project from a cmake folder, I get an error related to Xcode new build system. Any possible solution?

Question

I am trying to generate an Xcode project from a cmake folder, using this very good answer. When executing this command:

cmake -G Xcode <dir of CMakeLists.txt>

I get:

CMake Error in CMakeLists.txt:
  The custom command generating

    /Users/fofo/Developer/ClientProject/desktop/always_build

  is attached to multiple targets:

    rake-all
    stage

  but none of these is a common dependency of the other(s).  This is not
  allowed by the Xcode "new build system".


CMake Generate step failed.  Build files cannot be regenerated correctly.

Can I somehow specify to cmake -G Xcode to use the old Xcode build system, or can I somehow solve the problem changing the cmake files ? Any help is greatly appreciated. Thanks

Answer 1

I have found the answer here. It is possible to use the legacy build system using:

cmake -G Xcode -T buildsystem=1 .

Thanks a lot for your attention.
