如何将外部库与cmake链接？

Question

I am trying to build a project using CMake. One of the libraries that is required for the project is located on a path outside my project directory. The header files are scattered in sub-directories as well as in the root of the folder. A bit like this:

/some_remote_path/packages/BOOX/
               |-> foo.h
               |-> banana.h
               |-> orange.h
               |-> timer
                     |-> lib0.h
                     |-> lib1.h
                     |-> lib2.h
               |-> types
                     |-> type0.h
                     |-> type1.h
                     |-> type2.h
               ...

I am trying to link these using the following command:

include_directories (${SOME_OTHER_LIB_HEADERS} ${BOOX_HEADERS})

How can I store all the headers into the ${BOOX_HEADERS} variable? I tried many things such as various macros utilising the GLOB_RECURSE feature:

FILE(GLOB_RECURSE ${BOOX_HEADERS} ${path_to_boox_lib} *.h)

But without any success. I would like to skip writing a complex find.cmake script. That would have helped me (probably?) to generate something like ${BOOX_INCLUDE_DIRS}. What would be the best solution to simply construct the header list and pass it to the compiler using CMake.

I am trying to link these using the following command:

you are including header with the command you have given how would you also need to define LIBs path for the library with link_directories(directory1 directory2 ...)
