In Application_1/CMakeLists.txt, e.g., do:
SET(Library_1_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../Library_1
CACHE PATH "Library_1 source directory")
...
ADD_SUBDIRECTORY(${Library_1_SOURCE_DIR} Library_1)
Do the same for Library_2 and every other prerequisite project which
- has a source tree external to Application_1
- you want to be built along with the latter
and finally: TARGET_LINK_LIBRARIES(Application_1 Library_1 ...)
If the fallback value of Library_1_SOURCE_DIR once doesn't suit, you
can set it on the command line or in the GUI before (re)configuring.

Michael

Re: [CMake] Question regarding source tree structure and how to find libraries easily within that structure
Hello, thanks for the responses. The problem I have is, that we have more than one application in the directory. So if I put an CMakeLists.txt in the Src directory I do not have the choice (only by options). I would prefer a solution where I change into the application directory I want to build and create workspace etc. from there. The created workspace should then also build all necessary libraries for the application. Any ideas on this?

Re: [CMake] Question regarding source tree structure and how to find libraries easily within that structure
Hi Andreas,I too am new to CMake, but let me take a crack at this... someone correct me if there's a better way.You shouldn't need a find module. You only need them when you're including libraries that CMake doesn't already know the location of. Since you're building Library_1 in CMake you can just give the library target name directly to target_link_libraries.Assuming you have:Source/CMakeLists.txt ... add_subdirectory(Library_1) add_subdirectory(Application_1)Source/Library_1/CMakeLists.txt add_library(Library_1 then you can simply do this:Source/Application_1/CMakeLists.txt add_executable( Application_1 app1.cpp ) target_link_libraries( Application_1 Library_1 ) # That said, I'm not quite sure the nicest way to include_directories of said library. # I've been using this: include_directories( "${PROJECT_SOURCE_DIR}/Library_1" )Hope this helps,-Carl-cmake-boun...@cmake.org wrote: -To: cmake@cmake.orgFrom: "m.hergarden" Sent by: cmake-boun...@cmake.orgDate: 02/29/2012 01:50AMSubject: Re: [CMake] Question regarding source tree structure and how to find libraries easily within that structure

Is there a reason you can't use the
'include_directories' and 'link_directories' commands to add the
correct linkpaths?
