在 CMake 中添加对 NewT 的库引用 CMakeLists.txt

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 包：apt-get install libnewt-dev 我相信它安装正确，因为如果我使用 gcc 和以下命令进行构建，它工作得很好：

gcc -o test main.cpp -lnewt

但是当我尝试使用 cmake 使用新的 CLion IDE 时，我的简单代码无法编译。这是源代码，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;
}

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，但不知道该怎么做！所以基本上我正在寻找相当于 -l 开关 gcc 的 CMakeLists.txt

除了我的评论，经过一点搜索，我认为你需要命令''target_link_libraries'' http://www.cmake.org/cmake/help/v3.0/command/target_link_libraries.html
