Description Kevin Funk 2017-09-08 10:58:06 UTC 
Scenario:

I'd like to import:
  /home/kfunk/devel/src/llvm/tools/clang/tools/extra
The real top-level CMake source directory is:
  /home/kfunk/devel/src/llvm    
My build directory is: 
  /home/kfunk/devel/build/llvm 

As far as I understand importing the project this way actually works fine *in theory*. KDevelop build in release mode can open this; but sometimes hangs when importing the project. KDevelop built in debug mode crashes instantly.

Interesting log output:

kdevelop(31024)/kdevelop.projectmanagers.cmake: CMakeServer::handshake(174): Build directory is configured for another source directory: "CMAKE_HOME_DIRECTORY" "/home/kfunk/devel/src/llvm" wanted to open "/home/kfunk/devel/src/llvm/tools/clang/tools/extra" in "/home/kfunk/devel/build/llvm"

That assert should be relaxed one way or the other.
