cmake 模組的使用和自定義模組

參考《cmake教程》第9講：

目錄樹(沒有編譯，所以build資料夾為空)

)## 方法1

# 使用include_directories

()新增外部標頭檔案位址

# 使用target_link_libraries

()鏈結共享庫

# include_directories(/usr/include)

# add_executable(curltest main.c)

# target_link_libraries(curltest curl)

## 方法2 使用cmake提供的findcurl模組

# 系統預定義變數 _found,

_include_dir,

_library

add_executable

(curltest main.c)

find_package

(curl)

if(curl_found)

include_directories($)

target_link_libraries

(curltest $

)else

(curl_found)

message

(fatal_error "curl library not found! 2020.4.30"

)endif

(curl_found)

src/main.c

#include

#include
#include
#include
file *fp;
intwrite_data
(void
*ptr, size_t size, size_t nmemb,
void
*stream)
intmain()

find_path

(hello_include_dir hello.h /usr/include/hello 
/usr/local/include/hello)
find_library
(hello_library names hello path /usr/lib /usr/local/lib)
if(hello_include_dir and hello_library)
set(hello_found true)
endif
(hello_include_dir and hello_library)
if(hello_found)
if(not hello_find_quietly)
message
(status "found hello: $"
)endif
(not hello_find_quietly)
else
(hello_found)
if(hello_find_required)
message
(fatal_error "could not find hello library"
)endif
(hello_find_required)
endif
(hello_found)
message
(status "run findhello.cmake success!"
)

cmake_minimum_required

(version 2.8
)project
(hello_use_module)
set(cmake_module_path $
/cmake)
add_subdirectory
(src)

cmake_minimum_required

(version 2.8
)find_package
(hello)
if(hello_found)
add_executable
(hello main.c)
include_directories($)
target_link_libraries
(hello $
)endif
(hello_found)

#include

intmain()

如果程式中使用了外部庫，事先並不知道它的標頭檔案和鏈結庫的位置，就要給出標頭檔案和鏈結庫的查詢方法，並將他們鏈結到程式中。find package major.minor quiet no module required components componets.1 find package 的查詢...
