Visual Studio 2022 - cannot build project

I try to compile InsightToolkit-5.4rc01 on Win10 with cmake and VisualStudio 2022.
cmake error:
CMake Error at Modules/ThirdParty/VNL/src/vxl/CMakeLists.txt:222 (message):
You cannot have a + in your binary path

CMake Error at Modules/ThirdParty/VNL/src/vxl/CMakeLists.txt:225 (message):
You cannot have a + in your source path

CMake Error at Modules/ThirdParty/VNL/src/vxl/CMakeLists.txt:230 (if):
if given arguments:
“C:/C++/InsightToolkit-5.4rc01/build/Modules/ThirdParty/VNL/src/vxl” “MATCHES” “C:/C++/InsightToolkit-5.4rc01/Modules/ThirdParty/VNL/src/vxl”

Regular expression
“C:/C++/InsightToolkit-5.4rc01/Modules/ThirdParty/VNL/src/vxl” cannot
compile

Configuring incomplete, errors occurred!

What is going wrong?
Thanks

Are the error messages not sufficiently clear? CMake’s if (x MATCHES y) apparently expects a regex, and a + in it causes confusion. Perhaps VXL’s CMakeLists should be refactored as per this. Meanwhile, rename your C++ directory into Cpp or Cxx.

Oh God, sure - I was totally blind.
Thanks
