[CMake] cmake trouble

[Eric Clark]

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
