问题描述

我在一个项目中工作，我需要使用MySQL LIBRARIES。我以前有成功，使用一个简单的makefile，我写了具体的标志。

I'm working in a project where I need to use MySQL LIBRARIES. I had success in the past, using a simple makefile where I wrote the specific flags.

CFLAGS+=`mysql_config --cflags`
LIB+=`mysql_config --libs`

但是...对于我的项目是需要使用cmakelist，我有困难。我可以用这个代码添加GTK库：

However... for my project is required to use a cmakelist and I'm having difficulties with that. I can add GTK libraries with this code:

find_package(PkgConfig REQUIRED)
pkg_check_modules(GTK REQUIRED gtk+-3.0)

include_directories(${GTK_INCLUDE_DIRS})
link_directories(${GTK_LIBRARY_DIRS})
target_link_libraries( cgm ${GTK_LIBRARIES} )

但对于MySQL我有麻烦。我尝试了很多东西不成功，但我相信这是类似于GTK的例子。任何人都可以帮助我这个问题？

but for MySQL I'm in trouble. I tried many things unsuccessfully, but I believe that is similar to the GTK example. Can anyone help me with this problem?

推荐答案

最简单的方法可以是找到（例如用google） FindMySQL.cmake 脚本，它为您工作。此脚本可照常使用 find_package 命令：

The simplest way could be to find (e.g. with google) FindMySQL.cmake script, which works for you. This script can be used with find_package command as usual:

list(CMAKE_MODULE_PATH APPEND <directory-where-FindMySQL.cmake-exists>)
find_package(MySQL REQUIRED)

include_directories(${MYSQL_INCLUDE_DIR})
target_link_libraries(cgm ${MYSQL_LIB})

（变量名称 MYSQL_INCLUDE_DIR code> MYSQL_LIB 对于具体脚本可以是不同的）。

(Names of variables MYSQL_INCLUDE_DIR and MYSQL_LIB can be different for concrete script).

但是不难手动链接MySQL库，用于计算CFLAGS和LIBS。

But it is not difficult to link with MySQL library manually, knowing way for compute CFLAGS and LIBS.

在配置阶段（执行 cmake ）程序可以使用，用于为特定目标使用添加CFLAGS和LIBS 和：

During configuration stage(executing of cmake) programs can be run with execute_process, for add CFLAGS and LIBS for specific target use target_compile_options and target_link_libraries correspondingly :

execute_process(COMMAND mysql_config --cflags
    OUTPUT_VARIABLE MYSQL_CFLAGS)
execute_process(COMMAND mysql_config --libs
    OUTPUT_VARIABLE MYSQL_LIBS)

target_compile_options(cgm ${MYSQL_CFLAGS})
target_link_libraries(cgm ${MYSQL_LIBS})
