I'm trying to set up a test project looking like my own project just to get things working first and it looks like this:
/MainProject/inc/main.h
/MainProject/src/main.cpp
/LibProject/inc/test.h
/LibProject/src/test.cpp
I've found some tutorials, but I cant find out how to set up this when I have the inc and src folder? How would the CMakeLists.txt files look? Would I have one in /, one in each of the project folders? It seems like I dont need to have one in the inc and src folders?
You need a CMakeLists.txt
for each source subdirectory. Your structure should look something like this:
root
|-MainProject
| |-inc
| | '-main.h
| |-src
| | |-main.cpp
| | '-CMakeLists.txt
| '-CMakeLists.txt
|-LibProject
| |-inc
| | '-test.h
| |-src
| | |-test.cpp
| | '-CMakeLists.txt
| '-CMakeLists.txt
'-CMakeLists.txt
Content of root/CMakeLists.txt
:
project(MyProject)
add_subdirectory(MainProject)
add_subdirectory(LibProject)
Content of LibProject/CMakeLists.txt
and MainProject/CMakeLists.txt
:
add_subdirectory(src)
Content of LibProject/src/CMakeLists.txt
:
# Notice name prefix of this variable, set by CMake according
# to value given with "project()" in the root CMakeLists.txt.
include_directories(${MyProject_SOURCE_DIR}/LibProject/inc)
add_library(LibProject test.cpp)
Content of MainProject/src/CMakeLists.txt
:
include_directories(${MyProject_SOURCE_DIR}/MainProject/inc)
# I assume you want to use LibProject as a library in MainProject.
include_directories(${MyProject_SOURCE_DIR}/LibProject/inc)
link_directories(${MyProject_SOURCE_DIR}/LibProject/src)
add_executable(MainProject main.cpp)
target_link_libraries(MainProject LibProject)
Then configure and build with:
$ cd root
$ mkdir build
$ cd build
$ cmake ..
$ make
