CMake Error in CMakeLists.txt:
The "CXX_MODULE_STD" property on the target "nocxx26target" requires that
the "__CMAKE::CXX26" target exist, but it was not provided by the
toolchain. Reason:
(Toolchain does not support discovering `import std` support|Experimental `import std` support not enabled when detecting toolchain|Unsupported generator: [^\n]*)
CMake Generate step failed. Build files cannot be regenerated correctly.
