Question

我正在开展一个项目，我在project/lib/SOEM/中存储了一个现有的CMake库（https://github.com/OpenEtherCATsociety/SOEM）。

我的应用程序的来源位于project/src/

我有一个根CMakeLists.txt，它添加了两个子目录。

现在我的问题是如何将SOEM库链接到我的可执行文件和还使用没有相对路径的标题？

SOEM包含自己的CMakeLists.txt，如果可能，我会优先根本不接触。它构建了一个库并将其与头文件一起安装，但是，我不知道如何使用后者。

cmake_minimum_required(VERSION 2.8.4)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules")
project(SOEM C)

if (CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)
  # Default to installing in SOEM source directory
  set(CMAKE_INSTALL_PREFIX ${CMAKE_SOURCE_DIR}/install)
endif()

set(SOEM_INCLUDE_INSTALL_DIR include/soem)

if(WIN32)
  set(OS "win32")
  include_directories(oshw/win32/wpcap/Include)
  link_directories(${CMAKE_SOURCE_DIR}/oshw/win32/wpcap/Lib)
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} /D _CRT_SECURE_NO_WARNINGS")
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS}  /WX")
  set(OS_LIBS wpcap.lib Packet.lib Ws2_32.lib Winmm.lib)
elseif(UNIX)
  set(OS "linux")
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wall -Wextra -Werror")
  set(OS_LIBS pthread rt)
elseif(${CMAKE_SYSTEM_NAME} MATCHES "rt-kernel")
  set(OS "rtk")
  message("ARCH is ${ARCH}")
  message("BSP is ${BSP}")
  include_directories(oshw/${OS}/${ARCH})
  file(GLOB OSHW_EXTRA_SOURCES oshw/${OS}/${ARCH}/*.c)
  set(OSHW_SOURCES "${OS_HW_SOURCES} ${OSHW_ARCHSOURCES}")
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wall -Wextra -Werror")
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-unused-but-set-variable")
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-unused-function")
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-format")
  set(OS_LIBS "-Wl,--start-group -l${BSP} -l${ARCH} -lkern -ldev -lsio -lblock -lfs -lusb -llwip -leth -li2c -lrtc -lcan -lnand -lspi -lnor -lpwm -ladc -ltrace -lc -lm -Wl,--end-group")
endif()

message("OS is ${OS}")

file(GLOB SOEM_SOURCES soem/*.c)
file(GLOB OSAL_SOURCES osal/${OS}/*.c)
file(GLOB OSHW_SOURCES oshw/${OS}/*.c)

file(GLOB SOEM_HEADERS soem/*.h)
file(GLOB OSAL_HEADERS osal/osal.h osal/${OS}/*.h)
file(GLOB OSHW_HEADERS oshw/${OS}/*.h)

include_directories(soem)
include_directories(osal)
include_directories(osal/${OS})
include_directories(oshw/${OS})

add_library(soem STATIC
  ${SOEM_SOURCES}
  ${OSAL_SOURCES}
  ${OSHW_SOURCES}
  ${OSHW_EXTRA_SOURCES})
target_link_libraries(soem ${OS_LIBS})

install(TARGETS soem DESTINATION lib)
install(FILES
  ${SOEM_HEADERS}
  ${OSAL_HEADERS}
  ${OSHW_HEADERS}
  DESTINATION ${SOEM_INCLUDE_INSTALL_DIR})

add_subdirectory(test/linux/slaveinfo)
add_subdirectory(test/linux/eepromtool)
add_subdirectory(test/linux/simple_test)

在包含其标题的新项目中使用现有的CMake库
