I would like some advises on the organization of a set of related but independent C++ projects stored in a single (git) repository. The projects use CMake.For a simplified example we imagine 2 projects A and B, A depending on B. Most people developing A will get B via the packaging system. Thus they will compile only A. However, we should allow developers to compile both A and B themselves (and install it), separately or together.Here is a proposal :  Repo1     CMakeLists.txt (1)     A        CMakeLists.txt (2)        include           aaa.h           aaaa.h           CMakeLists.txt (3)        src            aaa.cpp            aaaa.cpp            CMakeLists.txt (4)     B        CMakeLists.txt (2)        include           bbb.h           bbbb.h           CMakeLists.txt (3)        src            bbb.cpp            bbbb.cpp            CMakeLists.txt (4)     test         CMakeLists.txt (5)         testaaaa.cpp(1) Define the common cmake variables for all projects (if any) and includes the subdirectories. (2) Defines the project itself and the project's required cmake variables.(3) Defines the headers to install and the ones required for compilation.(4) Configures the library and binaries.(5) Configures the test executables and test-cases.As I understand it, each project should produce a XXXConfig.cmake file and install it in /usr/local/share/cmake. Writing these files seem quite complicated when reading the documentation of CMake. What do you think ? Does the structure make sense ? Do you happen to have a working example of such a set of projects ? 
Directory organization of a CMake (C++) repository containing several projects
c++;organization;code organization;dependency management;cmake
After quite some reading and tests, I have made a basic demo C++ project demonstrating the use of CMake, CTest + boost.test, CPack and Doxygen and using more or less the organization I mentioned in my question.The project shows how to make subproject dependencies, how to compile the whole repo or only a subproject, how to package, how to test and how to produce documentation.See here : https://github.com/Barthelemy/CppProjectTemplate
