[CMake] Makefile to CMakeLists.txt (GTEST)

[Kevyn-Alexandre Paré]

Philip,

Thx for the reply. Neither of these solutions change a thing.

I try to play with ADD_CUSTOM_TARGET but same error...

ADD_CUSTOM_TARGET(RRThread.o ALL COMMAND ${CMAKE_C_COMPILER} -I
${MICRONTRACKER_COMMON_PATH} -I${GTEST_HEADER_PATH} -lpthread -c
${MICRONTRACKER_COMMON_PATH}RRThread.c
${UNIT_TEST_PATH}common/UT_RRThread.cc)

ADD_CUSTOM_TARGET(UT_RRThread ALL COMMAND ${CMAKE_CXX_COMPILER} -I
${MICRONTRACKER_COMMON_PATH} -I${GTEST_HEADER_PATH} -lpthread RRThread.o
UT_RRThread.o ${GTEST_LIB_PATH}gtest.a ${GTEST_LIB_PATH}gtest_main.a -o
UT_RRThread)

Result:
UT_RRThread.o: In function `thread_proc(void*)':
UT_RRThread.cc:(.text+0x28): undefined reference to `exitThread()'
...

I pretty sure that I'm missing little detail. How can I implicitly add
dependency to the object during the linking?

Regards
