Re: [CMake] Linker Include Path

[David Cole]

Can you put a CMakeLists.txt in the xyz directory, like this?

add_library(xyz xyz.c)


And then in the src/CMakeLists file, do:

add_subdirectory(xyz)
...
add_library(src ${SOURCES})
target_link_libraries(src xyz)

Or is there some reason that xyz.c must be in a different directory,
but the same library/executable as the files listed in SOURCES?

 Hi all,


 I'm using cmake (2.8.5) to build a set of C++ libraries. I have a project
 directory structure which is basically organized like this:


 package/component/CMakeLists.txt
 package/component/inc/foo.hpp
 package/component/src/foo.cpp


 Boiled down, my CMakeLists.txt for this component looks like this:


 SET(HEADERS inc/foo.hpp)
 SET(SOURCES src/foo.cpp)
 SET(LIBS whatever)
 INCLUDE_DIRECTORIES(inc)
 ADD_LIBRARY(MyLib ${HEADERS} ${SOURCES})
 TARGET_LINK_LIBRARIES(MyLib ${LIBRARIES})


 This has worked fine for me. Now, however, I would like to add another
 subdirectory to the src tree (this has organizational reasons), resulting in
 something like this:


 package/component/CMakeLists.txt
 package/component/inc/foo.hpp
 package/component/src/foo.cpp
 package/component/src/xyz/xyz.cpp


 I modified the SOURCES assignment in my CMakeLists.txt like so:


 SET(SOURCES src/foo.cpp src/xyz/xyz.cpp)


 While this does compile, it does not link. I assume that this is because the
 xyz.o is put in


 CURRENT_BINARY_OUTPUT/xyz/xyz.o


 and the linker does not include that subdirectory. If I move the source file
 up by one level (i.e. into the src directory), everything compiles and links
 just fine, but that's not really an acceptable solution. Is there some
 (portable) way to tell CMake to include the xyz output path so that xyz.o is
 found at link time?



 Thanks in advance for your help!

Sorry, never mind: Problem has resolved itself. The linker error was due 
to some other dependency.
