Hello All,

I am using CMake and UseSwig() to create some java bindings. All seems to work - but I get an error when trying to pass the “-package” option on to swig (in order to wrap the created java into a java package)

set(CMAKE\_SWIG\_FLAGS “-doxygen; -package com.package.example”)

Gives this error:

```auto
  Swig compile C:/Users/casht/repos/imatest_motion/build_Release/MC_API_JavaPackage/SwigInterface.i for java
CUSTOMBUILD : swig error : Unrecognized option -package com.package.example [C:\Users\casht\repos\imatest_motion\build_Release\MC_API_JavaPackage\MC_API_JavaPackage.vcxproj]
  Use 'swig -help' for available options.

```

I’m using cmake 3.25.1 and swig 4.1.1

Any help would be appreciated,  
-Trevor

It looks like the spaces are being taken literally. Try:

>
> ```cmake
> set(CMAKE_SWIG_FLAGS “-doxygen;-package;com.package.example”)
> 
> ```
