In Clion, unfortunately not 😅

And if I don't enforce ninja and use make instead:

Do I need to export some INCLUDES for Java?

Brunner246 commented 1 month ago

@munterfi the issue is that the header to the JNI interfaces can not be found 

'jni.h' file not found
#include "jni.h"

can you verify that the headers are located in 

elseif (APPLE)
    include_directories("$ENV{JAVA_HOME}/include/darwin")
    include_directories("$ENV{JAVA_HOME}/include/")

?
