我一直在尝试将最新版本的qextserialport包含到我正在处理的项目中。项目结构如下：
我的CMake文件目前是这样的：
PROJECT(CameraProject)
FIND_PACKAGE(Qt4 REQUIRED)
FIND_LIBRARY(SIMPLONLIB lv.simplon lib)
FIND_LIBRARY(SIMPLONIMGPROC lv.simplon.imgproc lib)
SET(CameraProject_SOURCES include/lv.simplon.class.cpp camera.cpp main.cpp mainwindow.cpp osdep.cpp paint.cpp)
SET(CameraProject_HEADERS include/lv.simplon.class.h camera.h mainwindow.h osdep.h paint.h)
SET(CameraProject_RESOURCES icons.qrc)
INCLUDE(${QT_USE_FILE})
ADD_DEFINITIONS(${QT_DEFINITIONS})
ADD_EXECUTABLE(CameraProject ${CameraProject_SOURCES}
${CameraProject_HEADERS_MOC}
${CameraProject_RESOURCES_RCC})
TARGET_LINK_LIBRARIES(CameraProject ${QT_LIBRARIES} ${SIMPLONLIB} ${SIMPLONIMGPROC})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR} include QExtSerialPort/src)
尽管在Include目录中包含了QextSerialPort文件，但我仍然会绘制链接器问题。
编辑：更多信息！
这里找到的是像CameraProject.pro中包含的qextserialport.pri文件，如下所示：include(./QExtSerialPort/src/qextserialport.pri)
我是否应该为源文件夹中放置的qextserialport库制作第二个CMakeLists文件？
非常感谢任何意见，请不要犹豫要求澄清或任何进一步的信息。

对qxt的作用是使用cmake finder模块而不是直接将代码包含到我的项目中。然后我用qmake构建了qxt，让CMake找到它创建的库。
#############
## basic FindQxt.cmake
## This is an *EXTREMELY BASIC* cmake find/config file for
## those times you have a cmake project and wish to use
## libQxt.
##
## It should be noted that at the time of writing, that
## I (mschnee) have an extremely limited understanding of the
## way Find*.cmake files work, but I have attempted to
## emulate what FindQt4.cmake and a few others do.
##
## To enable a specific component, set your QXT_USE_${modname}:
## SET(QXT_USE_QXTCORE TRUE)
## SET(QXT_USE_QXTGUI FALSE)
## Currently available components:
## QxtCore, QxtGui, QxtNetwork, QxtWeb, QxtSql
## Auto-including directories are enabled with INCLUDE_DIRECTORIES(), but
## can be accessed if necessary via ${QXT_INCLUDE_DIRS}
##
## To add the libraries to your build, TARGET_LINK_LIBRARIES(), such as...
## TARGET_LINK_LIBRARIES(YourTargetNameHere ${QXT_LIBRARIES})
## ...or..
## TARGET_LINK_LIBRARIES(YourTargetNameHere ${QT_LIBRARIES} ${QXT_LIBRARIES})
################### TODO:
## The purpose of this cmake file is to find what components
## exist, regardless of how libQxt was build or configured, thus
## it should search/find all possible options. As I am not aware
## that any module requires anything special to be used, adding all
## modules to ${QXT_MODULES} below should be sufficient.
## Eventually, there should be version numbers, but
## I am still too unfamiliar with cmake to determine how to do
## version checks and comparisons.
## At the moment, this cmake returns a failure if you
## try to use a component that doesn't exist. I don't know how to
## set up warnings.
## It would be nice having a FindQxt.cmake and a UseQxt.cmake
## file like done for Qt - one to check for everything in advance

我将此模块放在我的根项目的一个名为CMake / Modules的子目录中，并使用以下命令将其包含在根CMakeLists.txt顶部附近的cmake中：
# The following line will add additional finders to CMake without the need to be placed in the CMake install path
LIST(APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/CMake/Modules)
最后让CMake找到Qxt
SET(QXT_FIND_COMPONENTS QxtCore, QxtGui)
SET(QXT_USE_QXTCORE TRUE)
FIND_PACKAGE(Qxt REQUIRED)
