if(var) some_command(...) endif(var) ``` 循环结构:foreach和while ```cmake set(VAR a b c) loop over a, b,c with the variable f foreach(f ${VAR}) message(${f}) endforeach(f) ``` 过程定义 宏和函数(函数在2.6及更高的版本中有效)。函数对变量局部有效,宏是全局有效。
if(<variable|string> GREATER_EQUAL <variable|string>) 3.7 新版功能:如果给定的字符串或变量的值是有效数字并且大于或等于右边的数字,则为真。 if(<variable|string> STRLESS <variable|string>) 如果给定的字符串或变量的值按字典顺序小于右侧的字符串或变量,则为真。 if(<variable|string> STRGREATER <varia...
首先说明如何修改或创建一个环境变量,使用set(ENV{<variable>} <value>) 指令用以声明,使用unset(ENV{<variable>})来清除某一个环境变量,其中ENV表示环境变量标志性前缀,variable指变量名称,value则为变量值,需要注意的是设定或读取环境变量时,都通过ENV前缀来访问环境变量,读取环境变量值时,要在ENV前加$符号;但i...

4. SET(CMAKE_BUILE_TYPE DEBUG) 设置编译类型debug 或者release。 debug 版会生成相关调试信息,可以使用GDB 进行 调试;release不会生成调试信息。当无法进行调试时查看此处是否设置为debug. 5. SET(CMAKE_C_FLAGS_DEBUG "-g -Wall") 设置编译器的类型 CMAKE_C_FLAGS_DEBUG --- C 编译器 CMAKE_CXX_FLA...
Extra command-line options passed to rsync, a fast, versatile file-copying tool. CMake variables and cache These settings enable you to set CMake variables and save them in CMakeSettings.json. They're passed to CMake at build time, and override whatever values are in the CMakeLists.txt ...
Configure Cacheforces the generate step to run even if Visual Studio considers the environment up to date. Building CMake projects The CMake build step builds an already generated project binary tree. It's equivalent to invokingcmake --buildfrom the command line. For more information on the C...
Load on the command-line interface (CLI) starts immediately by selecting a toolchain, the set of utilities used to compile programs. To ease some of the toolchain related pains, CMake does consult theCCandCXXenvironmental variables when setting a defaultCMAKE_C[XX]_COMPILERrespectively, but that...
