Hello,
First off, you cannot call both add_executable and add_library in the same CMakeLists \
file. Here is what I can say about your other questions:
1. All commands that require a target have to come after you have created the \
target via add_executable or add_library. This is simply because you need to have a \
target before you can adds things to it.
2. I am not real sure why this would work. But, for common practices, you \
should always call target_link_libraries after your call to add_library or \
add_executable for the reason stated above.
3. Again, this is the same answer. It will work as long as you make the call to \
the command after add_library or add_executable.
Hope this helps.
Eric
