我在 /usr/lib 文件夹中有一个 libmosquittopp.so。mosquittopp.h 位于 /usr/include 文件夹中。
我喜欢将我的项目链接到那个库。
所以我的 CMakeLists.txt 文件是
cmake_minimum_required(VERSION 2.6)
PROJECT(MosquittoTest)
# The version number.
set (VERSION_MAJOR 1)
set (VERSION_MINOR 0)
include_directories("${PROJECT_BINARY_DIR}")
# Linked libariries
#For MQTT
#location of raspicam's cmake file is /usr/src/raspicam-0.1.3/build
link_directories(/usr/lib)
target_link_libraries (MosquittoTest mosquittopp)
ADD_EXECUTABLE(MosquittoTest MosquittoTest.cpp)
# add the install targets
install (TARGETS MosquittoTest DESTINATION bin)
install (FILES MosquittoInterface.h DESTINATION include)
但是当我在 ccmake GUI 中配置时，出现错误
Cannot specify link ibraries for target MosquittoTest which is not built by this project.
我的 cmake 有什么问题？
