Question

我的Travis-ci构建因未定义的引用而不断失败，这是构建日志

我该如何解决ncurses的“未定义引用”？我从源头构建了ncurses，并将'CMAKE_CXX_FLAGS'设置为“ -inccurses”，但我认为它似乎没有执行'CMAKE_CXX_FLAGS'。

用于非链接

cmake-

cmake_minimum_required(VERSION 3.9)
project(hoshiMenu)
include(FindPkgConfig)
pkg_check_modules(CURLPP REQUIRED curlpp)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

set(CMAKE_CXX_FLAGS "-lncurses")

add_executable(hoshiMenu main.cpp)
target_link_libraries(hoshiMenu ${CURLPP_LDFLAGS})

travis构建错误部分-
