As I said, the project using cgtools never went anywhere, so I never got 
to the point that I needed to worry about linker command files, so I can 
only give general hints, not a specific solution. That being said, 
setting CMAKE_LINKER will not work, because that specifies the 
executable to use as the linker. You could try adding 
CC11352P1_LAUNCHXL_TIRTOS.cmd with add_link_options() or 
target_link_options() like so:

target_link_options(<target> <path to CC1352P1_LAUNCHXL_TIRTOS.cmd>)


cmake should simply pass the command file through to the linker.

CMAKE_EXE_LINKER_FLAGS should be the correct place to do this if you 
want any target you build with this toolchain to use --rom_model. 
However, if you are going to set this in the toolchain file, you should 
set CMAKE_EXE_LINKER_FLAGS_INIT instead. This is because cmake will set 
CMAKE_EXE_LINKER_FLAGS based on the contents of 
CMAKE_EXE_LINKER_FLAGS_INIT and compiler-specific knowledge when it 
encounters the project() command after reading the toolchain file.

Alternatively, you could try adding the --rom_model using the 
add_link_options or target_link_options commands
