Summary:                    Use short switches for TI toolchain
Description: 
Currently TI support uses long options when compiling, but most of these options
have shorter versions. Longer versions can be problematic, since command line
length is limited (especially short on Windows) and, for example, having
multiple include directories prepended with '--include_path=' versus '-I' may
decide whether the build compiles or not.

I suggest to change at least the following (all suggestions using TI-C.cmake,
but suggestions are also appropriate for TI-CXX.cmake and TI-ASM.cmake):

Replace:
set(CMAKE_LIBRARY_PATH_FLAG "--search_path=")
set(CMAKE_LINK_LIBRARY_FLAG "--library=")
set(CMAKE_INCLUDE_FLAG_C "--include_path=")

With:
set(CMAKE_LIBRARY_PATH_FLAG "-I")
set(CMAKE_LINK_LIBRARY_FLAG "-l")
set(CMAKE_INCLUDE_FLAG_C "-I")

It would also be good to change other rules as well:

Replace:
set(CMAKE_C_CREATE_ASSEMBLY_SOURCE "<CMAKE_C_COMPILER> --compile_only
--skip_assembler --c_file=<SOURCE> <DEFINES> <FLAGS>
--output_file=<ASSEMBLY_SOURCE>")
set(CMAKE_C_CREATE_PREPROCESSED_SOURCE "<CMAKE_C_COMPILER> --preproc_only
--c_file=<SOURCE> <DEFINES> <FLAGS> --output_file=<PREPROCESSED_SOURCE>")

set(CMAKE_C_COMPILE_OBJECT  "<CMAKE_C_COMPILER> --compile_only --c_file=<SOURCE>
<DEFINES> <FLAGS> --output_file=<OBJECT>")
set(CMAKE_C_ARCHIVE_CREATE "<CMAKE_AR> -r <TARGET> <OBJECTS>")
set(CMAKE_C_LINK_EXECUTABLE "<CMAKE_C_COMPILER> --run_linker
--output_file=<TARGET> --map_file=<TARGET>.map <CMAKE_C_LINK_FLAGS>
<LINK_LIBRARIES> <LINK_FLAGS> <OBJECTS>")

With:
set(CMAKE_C_CREATE_ASSEMBLY_SOURCE "<CMAKE_C_COMPILER> -c -n -fc <SOURCE>
<DEFINES> <FLAGS> -fe <ASSEMBLY_SOURCE>")
set(CMAKE_C_CREATE_PREPROCESSED_SOURCE "<CMAKE_C_COMPILER> -ppo -fc <SOURCE>
<DEFINES> <FLAGS> -fe <PREPROCESSED_SOURCE>")

set(CMAKE_C_COMPILE_OBJECT  "<CMAKE_C_COMPILER> -c -fc <SOURCE> <DEFINES>
<FLAGS> -fe <OBJECT>")
set(CMAKE_C_ARCHIVE_CREATE "<CMAKE_AR> r <TARGET> <OBJECTS>")
set(CMAKE_C_LINK_EXECUTABLE "<CMAKE_C_COMPILER> -z -o <TARGET> -m <TARGET>.map
<CMAKE_C_LINK_FLAGS> <LINK_LIBRARIES> <LINK_FLAGS> <OBJECTS>")
