Thats not what the cmake manual states:
If COMMAND specifies an executable target (created by ADD_EXECUTABLE) it
will automat‐ ically be replaced by the location of the executable
created at build time.

So either the manual is wrong and one needs to manually construct the
correct paths even for in-project targets or cmake should prefer an
existing target over an executable reachable via PATH.
