add commit info. to test.log

[hiption]

Hi all

Including commit information in test.log would be beneficial for traceability.

There are two options for adding commit information to test.log

Option 1 : Using popen
popen("git rev-parse HEAD", "r")

Option 2 : Using CMAKE
execute_process(
COMMAND git rev-parse HEAD
WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}
OUTPUT_VARIABLE GIT_COMMIT_SHA
OUTPUT_STRIP_TRAILING_WHITESPACE
)
add_definitions(-DGIT_COMMIT_SHA="${GIT_COMMIT_SHA}")
