Hi,

When trying to build CC from source, I get the following error:

CMake Error at libs/CCAppCommon/CMakeLists.txt:24 (target_sources):
  Cannot find source file:

    /Users/abell/cc/libs/CCAppCommon/QDarkStyleSheet/qdarkstyle/dark/darkstyle.qrc

  Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm
  .ccm .cxxm .c++m .h .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90
  .f95 .f03 .hip .ispc

Can someone tell me what I'm missing or how to work around this?

Answering my own question:

I believe this is a dependency:

https://github.com/ColinDuquesnoy/QDarkStyleSheet

I will note that the building instructions seem to be out of date. You seem to now need Qt6 and there are dependencies and it's not made clear how best to integrate. I ended up just cloning projects into the expected places in the CC source tree and all seems well.

Correct, we have moved to Qt 6!
