[CMake] cmake: Duplicate file name conflict

[Jan Steinke]

Hi Peter,
Thanks for your quick reply.

My file structure is as such
someFolder/
                  library/code/include/*sameName.h*
                  library/code/include/anotherName.h
                  library/code/source/sameName.cpp
                  library/code/source/anotherName.cpp

                  application/code/include/*sameName.h*
                  application/code/include/yetAnotherName.h
                  application/code/source/*sameName.cpp*
                  application/code/source/yetAnotherName.cpp

*My CMakeLists.txt for the library:*
cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(library)
set(Headers include/sameName.h
                   include/anotherName.h)

set(Sources source/sameName.cpp
                   sources/anotherName.h)
set(CMAKE_AUTOMOC ON)
include_directories(include)
add_library(${PROJECT_NAME} STATIC ${Headers} ${Sources})
target_link_libraries(${PROJECT_NAME})

*CMakeLists.txt for the application:*
cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(application)
set(Headers include/sameName.h
                   include/yetAnotherName.h)
set(Sources source/sameName.cpp
                   source/yetAnotherName.cpp)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(LIBRARY_ROOT ${PROJECT_SOURCE_DIR}/../../library)

include_directories(include)
include_directories(include/remotes)
include_directories($LIBRARY_ROOT}/code/include)
include_directories(${PROJECT_BINARY_DIR}

add_subdirectory(${LIBRARY_ROOT}/code library)
add_executable(${PROJECT_NAME} ${Forms} ${Headers}
resources/${PROJECT_NAME}.qrc ${Sources})
target_link_libraries(${PROJECT_NAME} library)

I hope that helps understanding my problem. Since the content of sameName.h
and sameName.cpp of the library is different from those of the application
it doesn't build. However, it would be confusing to name them differently
since their job is the same.

Thanks in advance,
Jan
