Question

我正在尝试使用newt制作一个简单的TUI。我已经安装了newt-dev软件包：apt-get install libnewt-dev并且我相信它安装正确，因为如果我使用gcc使用以下命令构建，它可以正常工作：

gcc -o test main.cpp -lnewt

但是当我使用新cmake尝试使用CLion IDE时，我的简单代码无法编译。以下是源代码，CMakeLists.txt和编译器输出：

#include <newt.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char* argv[])
{

    /* required variables and string */
    int uiRows, uiCols;
    const char pcText[] = "Welcome to Newt and FLOSS !!!";

    /* initialization stuff */
    newtInit();
    newtCls();

    /* determine current terminal window size */
    uiRows = uiCols = 0;
    newtGetScreenSize(&uiCols, &uiRows);

    /* draw standard help and string on root window */
    newtPushHelpLine(NULL);
    newtDrawRootText((uiCols-strlen(pcText))/2, uiRows/2, pcText);

    /* cleanup after getting a keystroke */
    newtWaitForKey();
    newtFinished();

    return 0;
}

的CMakeLists.txt

cmake_minimum_required(VERSION 3.1)
project(TemparatureMonitoring)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
add_library(newt) #this does nothing!

set(SOURCE_FILES main.cpp)
add_executable(TemparatureMonitoring ${SOURCE_FILES})

编译器输出：

/opt/clion-1.0/bin/cmake/bin/cmake --build /home/saeid/.clion10/system/cmake/generated/9c100db8/9c100db8/Debug --target all -- -j 4
You have called ADD_LIBRARY for library newt without any source files. This typically indicates a problem with your CMakeLists.txt file

我想我必须以某种方式添加对newt包的引用，但不知道怎么做！所以基本上我正在为-l

寻找gcc CMakeLists.txt的等效转换

除了我的评论之外，在搜索了一下后，我认为您需要命令＆＃39;＆＃39; target_link_libraries＆＃39;＆＃39; http://www.cmake.org/cmake/help/v3.0/command/target_link_libraries.html

在CMake CMakeLists.txt中添加对NewT的库引用
