APPEND will append elements to the list. ... Similar to the SET command, the LIST command creates new variable values in the current scope, even if the list ...

The source file property will be set in each of the <dirs> directories' scopes. CMake must already know about each of these directories, either by having added them through a call to add_subdirectory () or it being the top level source directory. Relative paths are treated as relative to the current source directory.

Set a CMake, cache or environment variable to a given value. ... the parent gets the first chance to add a user-editable option to the cache.

The list subcommands APPEND , INSERT , FILTER , PREPEND , POP_BACK ... Similar to the set() command, the LIST command creates new variable values in the ...

Set a normal, cache, or environment variable to a given value. See the cmake-language(7) variables documentation for the scopes and interaction of normal ...

We found two ways to add a new argument pair to the CMAKE_ARGS of the external project. The first method uses the set function:

A function creates a new scope and inherit a copy of all variables defined in the upper scope. So, by adding a set command using ...

If cmake did this then there would be less need for the concat version of set() as one could just use the existing list(APPEND) ...

While a path can be created with care using an ordinary set() command, it is recommended to use cmake_path(SET) instead, as it automatically converts the path to the required form where required. The cmake_path(APPEND) subcommand may be another suitable alternative where a path needs to be constructed by joining fragments. The following example compares the three methods for constructing the same path:

local.cmake set(MY_VARIABLE "I am a variable") message(STATUS "${MY_VARIABLE}") ... Use include(CMakePrintHelpers) to add the useful commands ...

14.03.2017 · In CMake, a string of space -seperated items is just a string, not a list. Use the string (APPEND) command to append to it. For example: set (FOO "a") string (APPEND FOO " b") # now FOO="a b" string (APPEND FOO " c") # now FOO="a b c" On old versions of CMake that lack the string (APPEND) command, you should fallback to the set command.

A list in cmake is a ; separated group of strings. To create a list the set command can be used. For example, set (var a b c d e) creates a list with a;b;c;d;e, and set (var "a b c d e") creates a string or a list with one item in it. (Note macro arguments are not variables, and therefore cannot be used in LIST commands.)

21.03.2022 · CMake will evaluate SOMELIBs locations for you and link my_program against SOMELIB and SOMELIBmain [1]. Works for both Debug and Release configurations and also for Linux. You shouldn't have to worry where CMake places build files [2] and this is what so called "modern CMake" is trying to achieve.

It is possible for the cache entry to exist prior to the call but have no type set if it was created on the cmake(1) command line by a user through the -D<var>=<value> option without specifying a type. In this case the set command will add the type.

You can use the command line to set entries in the Cache with the syntax cmake -D var:type=value , just cmake -D var=value or with cmake -C ...

This command will set the value of a variable into the parent directory or calling function (whichever is applicable to the case at hand). The previous state of the variable's value stays the same in the current scope (e.g., if it was undefined before, it is still undefined and if it had a value, it is still that value). Set Cache Entry ¶

Aug 01, 2013 · set(MY_FLAGS "") set(MY_FLAGS "${MY_FLAGS} -Werror=shadow") set(MY_FLAGS "${MY_FLAGS} -Werror=return-local-addr") use list(APPEND) and replace ; with space; set(MY_FLAGS "") list(APPEND MY_FLAGS "-Werror=shadow") list(APPEND MY_FLAGS "-Werror=return-local-addr") string(REPLACE ";" " " MY_FLAGS "${MY_FLAGS}") use string(CONCAT). Note: this not means "append"

May 22, 2014 · This answer is not useful. Show activity on this post. I'm not sure whether you can directly add options from the command line, but you can use an additional variable to store them and merge it at the end. Like the following: set (CMAKE_CXX_FLAGS "$ {CMAKE_CXX_FLAGS} $ {MY_FLAGS}") And then call cmake as following: cmake -DMY_FLAGS="-new -flags".

Two things must be done. First add the directory to be included: target_include_directories(test PRIVATE ${YOUR_DIRECTORY}) In case you are stuck with a very old CMake version (2.8.10 or older) without support for target_include_directories, you can also use the legacy include_directories instead:. include_directories(${YOUR_DIRECTORY})

Set this parameter to None to avoid using it in the command line. ... The CMake helper will automatically append some definitions based on your settings: ...
