I wanted to make a simple layout like before by adding a new layout. While build is performed, I get an error

 In file included from /home/vega/MyApps/honza/Testing/main.cpp:1:0:
/home/vega/MyApps/honza/Testing/Testing.h:15:2: error: 'WithPltLayout1' does
     not name a type
  WithPltLayout1<ParentCtrl>doGeo;
  ^

• Is there really layout called PltLayout1? Check for typos...
• Is it in the .lay file that is properly included in Testing.h (using #define LAYOUTFILE <Testing/xyz.ly> with #include CtrlCore/lay.h following)?
• Is there some syntax error preceding this line, that would make your compiler report this as an error, while it is actually correct?
