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):

“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](https://github.com/vxl/vxl/blob/f5e08b6bd87ea3523531cbdd11e8d2f0c6b10be4/CMakeLists.txt#L228-L235) should be refactored as per [this](https://stackoverflow.com/a/22385516/276168). Meanwhile, rename your `C++` directory into `Cpp` or `Cxx`.

Oh God, sure - I was totally blind.
Thanks
