[CMake] Relinking static libs

[Jean Lepropre]

Ok, I have similar instructions and it does not work (relink is not done):


1. In top-level CMakeLists.txt:
...
ADD_SUBDIRECTORY(libs/bar)
ADD_SUBDIRECTORY(applications/foo)
...


2. In libs/bar/CMakeLists.txt:
...
ADD_LIBRARY(bar STATIC ...)
...


3. In applications/foo/CMakeLists.txt:
...
LINK_DIRECTORIES(${foo_BINARY_DIR}/../../libs/bar)
ADD_EXECUTABLE(foo ...)
TARGET_LINK_LIBRARIES(foo bar ...)
...


4. In generated applications/foo/CMakeFiles/foo.dir/build.make, there is 
no
dependence on libbard.a.

What's wrong?

Thanks for your help.

Cheers,
Jean.

No, if CMake is building the library as part of the project, you link it 
by the target name of the library.

Like this:

add_library(bar STATIC ...)
add_executable(foo ...)
target_link_libraries(foo bar)

CMake will recognize bar as the static library and put in the correct 
depend information.
