尝试将以下内容添加到 root CMakeLists.txt
:
CMAKE_MINIMUM_REQUIRED(VERSION 2.8.0)
PROJECT (ContainerProject)
SET (LIBRARY_OUTPUT_PATH ${ContainerProject_BINARY_DIR}/bin CACHE PATH
"Single output directory for building all libraries.")
SET (EXECUTABLE_OUTPUT_PATH ${ContainerProject_BINARY_DIR}/bin CACHE PATH
"Single output directory for building all executables.")
MARK_AS_ADVANCED(LIBRARY_OUTPUT_PATH EXECUTABLE_OUTPUT_PATH)
# for common headers (all project could include them, off topic)
INCLUDE_DIRECTORIES(ContainerProject_SOURCE_DIR/include)
# for add_subdirectory:
# 1) do not use relative paths (just as an addition to absolute path),
# 2) include your stuffs in build order, so your path structure should
# depend on build order,
# 3) you could use all variables what are already loaded in previous
# add_subdirectory commands.
#
# - inside here you should make CMakeLists.txt for all libs and for the
# container folders, too.
add_subdirectory(Libs)
# you could use Libs inside Apps, because they have been in this point of
# the script
add_subdirectory(Apps1)
add_subdirectory(Apps2)
在Libs
CMakeLists.txt
:
add_subdirectory(Source)
在Source
CMakeLists.txt
:
add_subdirectory(Lib1)
# Lib2 could depend on Lib1
add_subdirectory(Lib2)
这样所有人都Apps
可以使用所有库。所有二进制文件都将制作成您的二进制文件${root}/bin
。
一个示例库:
PROJECT(ExampleLib)
INCLUDE_DIRECTORIES(
${CMAKE_CURRENT_BINARY_DIR}
${CMAKE_CURRENT_SOURCE_DIR}
)
SET(ExampleLibSrcs
...
)
ADD_LIBRARY(ExampleLib SHARED ${ExampleLibSrcs})
一个示例可执行文件(具有依赖项):
PROJECT(ExampleBin)
INCLUDE_DIRECTORIES(
${CMAKE_CURRENT_BINARY_DIR}
${CMAKE_CURRENT_SOURCE_DIR}
${ExampleLib_SOURCE_DIR}
)
SET(ExampleBinSrcs
...
)
# OSX gui style executable (Finder could use it)
ADD_EXECUTABLE(ExampleBin MACOSX_BUNDLE ${ExampleBinSrcs})
TARGET_LINK_LIBRARIES(ExampleBin
ExampleLib
)
这是一个愚蠢而有效的例子。
