The suggestion for CMakeLists.txt

Dear CASToR Users and Developers,

The above code snippet that belongs to CMakeLists.txt

I think there need to set the variable first before calling the configure_file. Because the CASTOR_CONFIG cannot be defined fine in the oCASToRConfig.hh header file when using the CLion + WSL or VS 2022 + WSL. Other environments are fine.

Best Regards,
