Question

目前，我正在使用Raspberry Pi：

$ lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 8.0 (jessie)
Release:    8.0
Codename:   jessie

我有一些看起来像下面的图书馆(C language)：

my_app\-my_app.c
      \ - CMakeLists.txt
      \-lib
         \-lib1\- CMakeLists.txt
              \- src
                 \- lib1.c
                 \- CMakeLists.txt 
              \- include 
                 \- lib1.h 
              \- cmake
                    \- modules
                        \- FindGLIB2.cmake 
                        \- MacroOutOfSourceBuild.cmake
....................

lib1取决于glib

#include <glib.h>

这是我的CMakeLists.txt my_app

cmake_minimum_required(VERSION 2.8)

project(my_app)

set(CMAKE_MODULE_PATH ${my_app_SOURCE_DIR}/cmake/modules ${CMAKE_MODULE_PATH})

# Enable C11 or at least C99
include(CheckCCompilerFlag)
CHECK_C_COMPILER_FLAG("-std=c11" COMPILER_SUPPORTS_C11)
CHECK_C_COMPILER_FLAG("-std=c99" COMPILER_SUPPORTS_C99)
if(COMPILER_SUPPORTS_C11)
    message(STATUS "Using C11.")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -std=c11")
elseif(COMPILER_SUPPORTS_C99)
    message(STATUS "The compiler ${CMAKE_C_COMPILER} has no C11 support. Using C99 instead.")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -std=c99")
else()
    message(STATUS "The compiler ${CMAKE_C_COMPILER} has no C11 nor C99 support. Please update your C compiler.")
endif()

SET (CMAKE_C_FLAGS                "-lm")
include(MacroOutOfSourceBuild)
include(TargetDistclean)

macro_ensure_out_of_source_build("${PROJECT_NAME} requires an out of source build.")


add_subdirectory(lib/lib2)
add_subdirectory(lib/lib1)


include_directories(${lib2_SOURCE_DIR}/include)
include_directories(${lib1_SOURCE_DIR}/include)

# Add sources
set(my_app_SOURCES my_app.c)

add_executable(my_app ${my_app_SOURCES})

target_link_libraries(my_app
                    lib2
                    lib1
)

install(TARGETS my_app
    RUNTIME DESTINATION bin
)

这是我的CMakeLists.txt my_app/lib1

cmake_minimum_required(VERSION 2.8)

project(lib1)

set(CMAKE_MODULE_PATH ${lib1_SOURCE_DIR}/cmake/modules ${CMAKE_MODULE_PATH})

SET (CMAKE_C_FLAGS                "")
include(MacroOutOfSourceBuild)

macro_ensure_out_of_source_build("${PROJECT_NAME} requires an out of source build.")

add_subdirectory(src)

install(DIRECTORY include/lib1 DESTINATION include)

这是我的CMakeLists.txt my_app/lib1/src

# Include the directory itself as a path to include directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)

include(FindGLIB2)

include_directories(
    ${lib1_SOURCE_DIR}/include
    ${GLIB2_INCLUDE_DIRS}
)

set(lib1_SOURCES
lib1.c
)

add_library(lib1 ${lib1_SOURCES})
target_link_libraries(lib1
                    ${GLIB2_LIBRARIES}
)

install(TARGETS lib1 
    LIBRARY DESTINATION lib
    ARCHIVE DESTINATION lib
)

这是日志文件：

pi@raspberrypi ~/my_app/build $ cmake ..
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.28")

-- Build files have been written to: /home/pi/my_app/build

这意味着我的系统上已经有glib。

现在，我有这个问题：如果我仅将#include <glib.h>用于lib1.c。一切都很好。

如果我仅将#include <glib.h>用于lib1.h。我在lib1.h看到了这个问题：

lib1.h:2:18: fatal error: glib.h: No such file or directory
 #include <glib.h>
                  ^
compilation terminated.

EDITED

错误来自my_app.c，其中包括lib1.h

以下是VERBOSE=yes

与lib1.h

我对此有所了解。你能给我一些建议吗？

我不能在头文件中包含glib，但我可以在源文件中包含Raspberry Pi
