• Operation System: eCos
• Compilers for C:     arm-elf-gcc 
• and for C++:  arm-elf-g++
• Need to include path if not installed under cygwin
• path to target  
• Usually same as path to build binaries
• This has to be changed when ever workspace / file location changes
• then
• clear cache (will not clear the toolchain default)
• choose options and press configure.
• enter the text file with the options like below and press configure

INCLUDE(CMakeForceCompiler)

# this one is important
SET(CMAKE_SYSTEM_NAME eCos)

# specify the cross compiler

# where is the target environment 
SET(CMAKE_FIND_ROOT_PATH  C:/Users/Carolyn/Desktop/DistCntl/lms/forte012811WS/FORTE/bin/lms)
