I have the following in my lists:

add_custom_command(TARGET CustomTarget PRE_BUILD

  USES_TERMINAL
  )

In my output I get:
TARGET CustomTarget
CMake Error at Some/Path/CMakeLists.txt:52 (add_custom_command
):
  The target name "CustomTarget" is unknown in this context.

It seems like the if() shows that there is a target with the desired name. Am I missing something?

You can only modify a target after it has been defined and in the directory (CMakeLists.txt) that defined it.
The same goes for appending commands to targets.
