如何在CMake的外部库中包含头文件

raspberry-pi cmake build c

here . 我可以跑了 cmake. -DCMAKE_TOOLCHAIN_FILE 没有任何问题,但“make”命令不成功,并且在一个外部库中找不到头文件:“mirsdrapi rsp”。错误消息是:

fatal error: mirsdrapi-rsp.h: No such file or directory
 #include "mirsdrapi-rsp.h"
                           ^
compilation terminated.

我已经创建了一个名为“lib”的文件夹,并将“libmirsdrapi-rsp.so公司“文件在里面。我的CMakeLists.txt 具体如下:

cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_C_STANDARD 11)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_C_STANDARD_REQUIRED ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wall -pedantic -Wextra -v -g -D_XOPEN_SOURCE")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -pedantic -Wextra -v ")
set(CMAKE_EXE_LINKER_FLAGS  ${CMAKE_EXE_LINKER_FLAGS} "-v")
set (SDR_API_PATH ${CMAKE_SOURCE_DIR}/lib)
include_directories (include ${SDR_API_PATH})

include_directories("${CMAKE_SOURCE_DIR}/lib")

find_library(mirslocation NAMES mirsdrapi-rsp HINTS ${SDR_API_PATH} NO_CMAKE_FIND_ROOT_PATH)
message(STATUS ${mirslocation})

add_library(mirs STATIC IMPORTED)
set_target_properties(mirs PROPERTIES IMPORTED_LOCATION ${mirslocation})

target_link_libraries (raspberryPiDaemon mirs)
target_link_libraries(raspberryPiDaemon m)

Cmake在运行“find\u library”时正在打印库mirsdrapi rsp的正确路径,正如我所提到的,我只是在运行“make”命令而不是“Cmake”命令时收到错误消息。我的CMAKE\u TOOLCHAIN\u文件的内容如下:

# Define our host system
SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)

# Define the cross compiler locations
SET(CMAKE_C_COMPILER   ${CMAKE_SOURCE_DIR}/../tools-master/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER ${CMAKE_SOURCE_DIR}/../tools-master/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc)

# Define the sysroot path for the RaspberryPi distribution in our tools folder 
SET(CMAKE_FIND_ROOT_PATH ${CMAKE_SOURCE_DIR}/../tools-master/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/arm-linux-gnueabihf/sysroot/SET)


# Use our definitions for compiler tools
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# Search for libraries and headers in the target directories only
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY BOTH)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE BOTH)

add_definitions(-Wall -std=c11)

更准确地说:您需要找到mirsdrapi rsp.h的路径,并让CMake知道它,就像find\u库一样:

find_path(MIRSDRAPI_INCLUDE_DIRS NAMES mirsdrapi-rsp.h PATHS {proper-location})

if (MIRSDRAPI_INCLUDE_DIRS)
  target_include_directories(raspberryPiDaemon PRIVATE ${MIRSDRAPI_INCLUDE_DIRS})
endif()

此外,您可以将INTERFACE\u INCLUDE\u DIRECTORIES属性设置为库,如下所示:

set_property(TARGET mirsdrapi-rsp APPEND PROPERTY INTERFACE_INCLUDE_DIRECTORIES ${MIRSDRAPI_INCLUDE_DIRS})
