You must use a FULL path to the library or CMake will not know what
depend information to add. If you have:
add_executable(foo foo.c)
link_directories(foobar)
target_link_libraries(foo A B C)
And A, B and C are libraries in the foobar directory that are not built
by CMake, then there will be no depends on the external libraries as
CMake does not know where they are.
The correct thing to do would be:
find_library(ALIB A)
find_library(BLIB B)
find_library(CLIB C)
target_link_libraries(foo "${ALIB}" "${BLIB}" "${CLIB}")
Then CMake will have the full path to A,B, and C, and if one of them
changes foo will be relinked.
Thanks. It works now.
