Evaluate a group of commands for each value in a list.

List cache variables will run CMake and list all the variables from the CMake cache that are not marked as INTERNAL or ADVANCED. This will effectively display current CMake settings. If A is specified, then it will display also advanced variables. CMake is controlled by writing instructions in CMakeLists.txt files. Each directory in your project should have a CMakeLists.txt file. What is nice about CMake is that CMakeLists.txt files in a sub-directory inherit properties set in the parent directory, reducing the amount of code duplication. For our sample project, we only have one subdirectory: w01-cpp. Cmake./src && make Binaries by default go into the directory where you start cmake The argument is the directory where the starting CMakeLists.txt lives.
where is a list of items that are separated bysemicolon or whitespace.All commands between foreach and the matching endforeach are recordedwithout being invoked. Once the endforeach is evaluated, the recordedlist of commands is invoked once for each item in .At the beginning of each iteration the variable loop_var will be setto the value of the current item.
The commands break() and continue() provide means toescape from the normal control flow.
Per legacy, the endforeach() command admitsan optional argument.If used, it must be a verbatimrepeat of the argument of the openingforeach command. Microsoft visual c++ all in one.
In this variant, foreach iterates over the numbers0, 1, .. up to (and including) the nonnegative integer .
In this variant, foreach iterates over the numbers from up to at most in steps of .If is not specified, then the step size is 1.The three arguments mustall be nonnegative integers, and must not besmaller than ; otherwise you enter the danger zoneof undocumented behavior that may change in future releases.
In this variant, is a whitespace or semicolonseparated list of list-valued variables. The foreachcommand iterates over each item in each given list.The following the ITEMS keyword are processedas in the first variant of the foreach command.The forms LISTSA and ITEMS${A} areequivalent.
The following example shows how the LISTS option isprocessed:
Cmake Foreach Example
yields
New in version 3.17.

In this variant, is a whitespace or semicolonseparated list of list-valued variables. The foreachcommand iterates over each list simultaneously setting theiteration variables as follows:
if the only
loop_vargiven, then it sets a series ofloop_var_Nvariables to the current item from thecorresponding list;if multiple variable names passed, their count should matchthe lists variables count;
if any of the lists are shorter, the corresponding iterationvariable is not defined for the current iteration.
Cmake Foreach List
yields
