You may want to move this to https://discourse.cmake.org/, as this mailing list
is going away (note, Im not with the cmake org at all.. just a user..)
That said,typically, when a CMake based library is included into a larger cmake
project, it will set some variables. SUBLIB_DIR for instance.. so you would
then, in the top project do something like
include_directories( ${SUBLIB_DIR }/include )
If it doesn't create the directory, I would do the following
set( SUBLIB_DIR ${CMAKE_SOURCE_DIR}/SubLibName )
add_subdirectory( ${SUBLIB_DIR} )
for the output of the library, you can in your executable target_link_libraries
directly list the target project name
target_link_libraries( MyExe SubLib )

Subject: [CMake] Build cmake dependency
Hi all,
I really cannot say I am an expert with CMake however I have been using it for
a while now, even though mainly by copying and pasting snippet of code from the
web therefore not understanding things properly.
I am working on a project which depends on a libary which is itself built using
CMake, I'd like my project to build the library itself during its own build and
I can successfully do that by adding the folder to the root CMakeLists.txt of
my current prject, however I couldn't find a way to include its headers and
link the shared object.
I had to resort to a bash script which compiles and installs the dependency in
a pre-defined location and add such location to my project's CMake's setting
file through the use of include_directories()/link_directories(). It works but
I'd like to get CMake to do what I want and not having to find workaroun, I am
pretty confident I am missing something here, is there a better way to do that ?
Thanks,
Pietro
