O/H Gerrick Bivins ??????:
Hello,
Another newbie question, I think I know how to create .java files from
swig using Cmake and I think I know how to create a jar file from
.class BUT
I'm not sure how to call the java compiler (javac) on each .java file
to create my .class files. For starters, how would I loop over the
*.java files in a given directory?
Does, FOREACH support this? I'm unable to find much info on it in the
"Mastering Cmake" book.

Dear Gerrick,
I am not sure if this is the correct answer (I am also a newbie :-) ),
but I have added these commands to my CMakeLists.txt:
