I'm trying to make the vtk library depend on copperspice instead of qt. I'm running into the following issues:
1. I selected vulkan when compiling copperspice from source, and when I tried to link with vtk, an error occurred. So I unselected vulkan, will this have any effect? ​​Or, how should I fix this error?

cmake error message
/*
CMake Error at F:/CopperSpice/bin/cmake/CopperSpice/CopperSpiceLibraryTargets.cmake:130 (set_target_properties):
The link interface of target "CopperSpice::CsVulkan" contains:

Vulkan::Vulkan

but the target was not found. Possible reasons include:

* There is a typo in the target name.
* A find_package call is missing for an IMPORTED target.
* An ALIAS target is missing.
*/

2. qMove is not defined.

template <typename T>
class QScopedValueRollback
{
public:
explicit QScopedValueRollback(T &var, T value)
: varRef(var), oldValue(var)
{
varRef = qMove(value);
}
}；

Thanks for your questions and we are happy to support you in this migration project.

1) This error message indicates CMake was able to find the CopperSpice::CsVulkan library, but it has not been able to locate the LunarG Vulkan SDK. As the message mentions, you will need to add "find_package(Vulkan)" to your CMake project. You may also need to adjust your CMAKE_PREFIX_PATH so CMake can find the Vulkan SDK.

2) Thank you, we have now changed the qMove to call std::move.

Thank you very much for helping me solve the problem.

I encountered a new problem, Q_DECLARE_FLAGS macro is not defined.
https://www.copperspice.com/docs/cs_overview/m_macros_metaobj.html

This macro was removed in favor of a using declaration.
Thanks for letting us know about the documentation issue and please continue to tell us about anything which is missing or unclear. New CS Overview docs will be uploaded next week.
