Hi Bill:
Thanks, it's exactly what you mentioned, and I got some mistake on my
CMakeList.txt.
Originally I have some syntax like:
SET(LIB_DIRS ${LIB_DIRS} ${CMAKE_CURRENT_SOURCE_DIR}/../../../lib)
SET(LIBS ${LIBS} "libMyLibA.a")
TARGET_LINK_LIBRARIES(${PROGNAME} ${LIBS})
And I suddenly found out the usage was wrong and just too stupid ..
although it works on my first make.
However it would't relink when ../../../lib/libMyLibA.a got updated.
After I changed to:
SET(LIB_DIRS ${LIB_DIRS} ${CMAKE_CURRENT_SOURCE_DIR}/../../../lib)
SET(LIBS ${LIBS} "MyLibA")
TARGET_LINK_LIBRARIES(${PROGNAME} ${LIBS})
// or
SET(LIBS ${LIBS} "../../../lib/libMyLibA.a")
TARGET_LINK_LIBRARIES(${PROGNAME} ${LIBS})
Both works when libMyLibA got updated.
Now it works fine. And thank you.
