Cmake基本库链接问题 [英] Cmake basic library linking problem

问题描述

我有一个简单的问题，链接库与CMake（我不知道CMake很好）。
我的配置如下：

  project / src / CMakeLists.txt（所有.cpp和.h文件）
 project / support / linux / gmp / include / gmp.h 
 project / support / linux / gmp / include / gmpxx.h 
 project / support / linux / gmp / include / libgmp .a 
 project / support / linux / gmp / include / libgmpxx.a 
  

包括库gmp在编译过程中？ （我失去了FIND_PACKAGE，INCLUDE_DIRECTORIES，TARGET_LINK_LIBRARIES，ADD_LIBRARY ...命令）

非常感谢。

第一步

$ b

使用 find_package 找到库。

  find_package（GMP REQUIRED）
  

第二步

使用 include_directories 以包含库头文件。

  include_directories（$ {GOBJECT_INCLUDE_DIR}）
  

第三步

使用 target_link_libraries 将您的二进制文件链接到库。

  add_executable（ExecutableName Main.cpp）
 target_link_libraries（ExecutableName $ {GOBJECT_LIBRARIES}）
  

I have a simple problem with the linking of libraries with CMake (I don't know CMake very well). My configuration is the following :

project/src/CMakeLists.txt (with all .cpp and .h files)
project/support/linux/gmp/include/gmp.h
project/support/linux/gmp/include/gmpxx.h
project/support/linux/gmp/include/libgmp.a
project/support/linux/gmp/include/libgmpxx.a

How to include the library gmp in the process of compilation ? (I am lost between FIND_PACKAGE, INCLUDE_DIRECTORIES, TARGET_LINK_LIBRARIES, ADD_LIBRARY ... commands)

Thank you very much.

解决方案

CMake is not so hard to understand.

First Step

Use find_package to locate the libary.

find_package(GMP REQUIRED)

Second step

Use include_directories to include the libary header files.

include_directories(${GOBJECT_INCLUDE_DIR})

Third Step

Use target_link_libraries to link your binary against the libary.

add_executable(ExecutableName Main.cpp)
target_link_libraries(ExecutableName ${GOBJECT_LIBRARIES})
