前言
复习一下CMakeList.txt的写法,以下面的一个CMakeList.txt为例
一个最近写好的CMakeList.txt

对上边CMakeList.txt的说明
cmake_minimum_required(VERSION 3.17): 指定项目所需的最低CMake版本。project(QtVTKProject): 指定项目名称为"QtVTKProject"。#======================= INCLUSION OF Qt =======================#set(CMAKE_INCLUDE_CURRENT_DIR ON): 设置CMake包含当前目录。set(CMAKE_AUTOMOC ON): 设置自动运行moc（Meta-Object Compiler）工具，用于处理Qt的元对象系统。set(CMAKE_AUTOUIC ON): 设置自动运行uic（User Interface Compiler）工具，用于处理Qt的UI文件。set(CMAKE_PREFIX_PATH $ENV{QTDIR}): 设置Qt的安装路径。find_package(OpenGL): 查找OpenGL库。find_package(Qt5Core REQUIRED): 查找并要求Qt5Core库。find_package(Qt5Gui REQUIRED): 查找并要求Qt5Gui库。find_package(Qt5OpenGL REQUIRED): 查找并要求Qt5OpenGL库。find_package(Qt5Xml REQUIRED): 查找并要求Qt5Xml库。find_package(Qt5Widgets REQUIRED): 查找并要求Qt5Widgets库。#======================= INCLUSION OF VTK ======================#set(VTK_DIR $ENV{VTK_DIR}): 设置VTK的安装路径。find_package(VTK REQUIRED): 查找并要求VTK库。include(${VTK_USE_FILE}): 包含VTK的使用文件。#======================= INCLUSION OF Our Code ======================#set(FORMS_DIR "${CMAKE_SOURCE_DIR}/forms"): 设置forms目录的路径。set(INCLUDE_DIR "${CMAKE_SOURCE_DIR}/include"): 设置include目录的路径。set(SOURCE_DIR "${CMAKE_SOURCE_DIR}/src"): 设置src目录的路径。include_directories(${FORMS_DIR}): 包含forms目录以供编译器搜索ui文件。include_directories(${INCLUDE_DIR}): 包含include目录以供编译器搜索头文件。include_directories(${SOURCE_DIR}): 包含src目录以供编译器搜索源文件。file(GLOB_RECURSE SOURCES ...): 使用GLOB_RECURSE命令获取指定目录下的所有源文件。set(CMAKE_AUTOUIC_SEARCH_PATHS ...): 将forms目录添加到AUTOUIC搜索路径。if (WIN32) ... elseif(UNIX) ... endif(): 根据操作系统类型选择生成可执行文件的选项。
在Windows上使用WIN32选项，而在Unix上不包含此选项。add_executable(QtVTKProject ... ${SOURCES}): 添加可执行文件的构建目标，并指定源文件。target_include_directories(QtVTKProject PRIVATE ...): 为目标添加私有的包含目录。#===================== LINKING LIBRARIES =======================#target_link_libraries( QtVTKProject ...): 链接所需的库文件到目标。最后，该CMakeLists.txt文件的主要目标是构建一个名为"QtVTKProject"的可执行文件。它依赖于Qt和VTK库，并包含了一些源文件和UI文件。通过设置相关的包含目录和链接库，确保了项目的正确构建和链接。
修改
如果只需要Qt库的话,可以简单修改一下:
