CMakeLists.txt: 将main.cpp加入工程; 然后查找并链接opencv库 # cmake needs this linecmake_minimum_required(VERSION3.1)# Define project nameproject(opencv_example_project)# Find OpenCV, you may need to set OpenCV_DIR variable# to the absolute path to the directory containing OpenCVConfig.cmake ...
It sets the given <cachevariable> to a command-line string as above but without the --target option. The <makecommand> is ignored but should be the full path to msdev, devenv, nmake, make or one of the end user build tools for legacy invocations. Note In CMake versions prior to 3.0...

//No help, variable specified on the command line. EXECUTABLE_OUTPUT_PATH:UNINITIALIZED=bin 这样,可以在CMakeLists.txt文件中读取该变量的值。例如:message(${EXECUTABLE_OUTPUT_PATH}) -U <globbing_expr>: 此选项可用于从CMakeCache.txt文件中删除一个或多个变量,支持使用*和?的匹配。与-D对应,使用是须...
NEWLINE_STYLE <style>设置换行符格式。 举例: 文件如下 #cmakedefine FOO_ENABLE #cmakedefine FOO_STRING "@FOO_STRING@" 1. 2. CMakeLists.txt中添加代码来设置一个开关,下边会执行if中的语句: option(FOO_ENABLE "Enable Foo" ON) if(FOO_ENABLE) ...
# set(<variable> <value>... CACHE <type> <docstring> [FORCE]) set(CACHE_VAR "Default cache value" CACHE STRING "A sample for cache variable") 要点: 主要为了提供可配置变量,比如编译开关; 引用CACHE变量:$CACHE{<varialbe>}。 Cache变量会被保存在构建目录下的CMakeCache.txt中,缓存起来之后是不...
