CCS: Program "make" not found in PATH

Tool/software: Code Composer Studio

while trying to build a project in CCS 7.1.0, i find this error: 

Program "make" not found in PATH

the project does not build. i find this problem to exist with CCS 5.5 but even with CCS7.1.0 i am facing this problem. i have been though the earlier references to this problem and have tried creating a new workspace but it did not work for me. I also tried changing the build configuration from Debug (active) to Release because now i can check the "use default build command" option and this changes my build command to ${CCS_UTILS_DIR}/bin/gmake-k  but even this does not help solve the problem. 

im working on a DSP TMS32F2812 board and i am using TI XDX1--v2 USB debug probe. please help
