Question

我之前从未使用过CMake，所以请原谅。

我的项目有一个“unity”文件夹，其中包含2.3.0版的单元测试库。 unity_fixture.h包含“#define TEST（...”，其使用如下：

#include "unity_fixture.h" ... TEST(xformatc, Simple) { char output[20]; TEST_ASSERT_EQUAL(13, testFormat(output, "Hello world\r\n")); TEST_ASSERT_EQUAL_STRING("Hello world\r\n", output); }

我在我的CMakeLists.txt文件中添加了“include_directories（$ {CMAKE_SOURCE_DIR} / unity）”。仍然CLION没有找到TEST的声明，我得到了大量的错误。我确实试图用set（SOURCE_FILES unity / unity_fixture.h ......）添加所有统一文件，但这也不起作用。

编辑08.09.2015 我发现了一些奇怪的东西。如果我从命令行调用cmake，它会创建一个文件“DependInfo.cmake”，其中包含以下内容：

# The set of languages for which implicit dependencies are needed: set(CMAKE_DEPENDS_LANGUAGES ) # The set of files for implicit dependencies of each language:



# Targets to which this target links.
set(CMAKE_TARGET_LINKED_INFO_FILES
  )

# The include file search paths:
set(CMAKE_C_TARGET_INCLUDE_PATH
  "unity"
  "cmsis/inc"
  "freertos/inc"
  )
set(CMAKE_CXX_TARGET_INCLUDE_PATH ${CMAKE_C_TARGET_INCLUDE_PATH})
set(CMAKE_Fortran_TARGET_INCLUDE_PATH ${CMAKE_C_TARGET_INCLUDE_PATH})
set(CMAKE_ASM_TARGET_INCLUDE_PATH ${CMAKE_C_TARGET_INCLUDE_PATH})

# Targets to which this target links. set(CMAKE_TARGET_LINKED_INFO_FILES ) # The include file search paths: set(CMAKE_C_TARGET_INCLUDE_PATH "unity" "cmsis/inc" "freertos/inc" ) set(CMAKE_CXX_TARGET_INCLUDE_PATH ${CMAKE_C_TARGET_INCLUDE_PATH}) set(CMAKE_Fortran_TARGET_INCLUDE_PATH ${CMAKE_C_TARGET_INCLUDE_PATH}) set(CMAKE_ASM_TARGET_INCLUDE_PATH ${CMAKE_C_TARGET_INCLUDE_PATH})

CLion创建的文件中缺少CMAKE_C_TARGET_INCLUDE_PATH。我相信这就是它找不到标题的原因。问题是如何告诉CLion创建CMAKE_C_TARGET_INCLUDE_PATH的东西？

我假设你的项目结构是：

project root
├── CMakeLists.txt
├── Some source files
└── unity
    └── unity_fixture.h

如果您使用CMake包含文件：

set(INCLUDE_DIR ./unity)
include_directories(${INCLUDE_DIR})

您的收件人必须是：#include <unity_fixture.h>

或者您可以在不使用CMake的情况下使用以包含目录：#include "unity/unity_fixture.h"

Clion 1.1.1使用CMakeList.txt为统一添加库头
