CMake how to force third_party library include the project file in current project source directory? [duplicate]

I have a pre-compiled dependency library A which has only include/ and lib/

A was built with system library B which was installed in /usr/local/include/B/ and /usr/local/lib/B

But on my building system doesn't have library B and do not allow me to modify the system (no privilege).

I downloaded B and put B_include in local project C's include directory and B_lib in C's lib directory.

I tried in CMakeList.txt of local project:

include_directories(
    C_INCLUDE_DIR
    B_INCLUDE_DIR
)

link_directories(
    C_LIB_DIR
    B_LIB_DIR
)

But when compile C against library A, A's include can not find the local header file B_INCLUDE_DIR. Does anyone know how to force CMake to find the local library file other than directly navigate into system include and lib directories?

To sum up, can I tell CMake to force a pre-compiled library to use local include file?

"But it doesn't work"... This is a pretty vague problem description. Could you please describe how it doesn't work, including any relevant error messages or undesired behaviors. Also, it looks like this question addresses something very similar to what you're asking. Specifically, link_directories() doesn't actually link the libraries, it only provides an additional path to the linker for library searching. - Kevin

Just solved the problem. It turn out to be my own mistake. Thanks to squareskittles's comments.

the following CMakeList commends will do the work nicely:

include_directories(
    C_INCLUDE_DIR
    B_INCLUDE_DIR
)

link_directories(
    C_LIB_DIR
    B_LIB_DIR
)

rosbuild_add_executable(your_executable src/your_source_file.cpp)

TARGET_LINK_LIBRARIES(your_executable lib1.so lib2.so lib3.so ...)
