Cmake Set Compiler Variable

It needs to be set to either 5 or 6 before the respective find package calls. To extend the scope of a variable there are two possibilities. Variables meaningful to cmake such as cmake lang flags are propagated automatically.

I want to work on project that needs make cmake and mingw so i need to setup my environment so that cmake can access a compiler g or gcc.

Cmake set compiler variable. For general information on variables see the variables section in the cmake language manual. Thanks for the advice however i ve already tried setting the compiler via environment variable and got the same result as setting it via cmake option dcmake c. Cmake cross platform make is a relatively new build system that is gaining in popularity. It is meant to be set by cmake s platform information modules for the current toolchain or by a toolchain file when used with cmake toolchain file.

Or use a gui. A lot of variables used by cmake are set with the project and enable language calls. At last the source list is nothing someone suggested that to use macro instead of function but i do need use local variable so i need to use the function instead of macro. One of the biggest selling points is its ability to manage native builds on ms windows.

How can i correctly set the global variable source list in the function test. Environment variables may differ from where cmake generated the make environment and when the the make files are put to use. This is so common you can also use the internal type to do the same thing though technically it forces the string type this won t affect any cmake code that depends on the variable. Starting with the 4 5 release it is possible to configure and compile the source code with it.

An integer that controls the qt version that qt commands forward to in case of mixed qt 5 and qt 6 projects. This variable should not be set by project code. If set to 5 commands starting with qt will call their counterpart starting with qt5 if set to 6 they will call their counterpart starting with qt6. I have install all the tools and i m having errors tell cmake where to find the compiler either by setting the environment variable cc like liked by 1 person.

So it could get important to set some variables before those commands are used. Example set my variable the value is a string by default a local variable is only defined in the current directory and any subdirectories added through the add subdirectory command. This page documents variables that are provided by cmake or have meaning to cmake when set by project code. The first line will cause the value to be set no matter what and the second line will keep the variable from showing up in the list of variables if you run cmake l.

Ymmv and if this doesn t work in your environment i believe you but i want to emphasize the difference between setting cc and cxx versus setting cmake c compiler and cmake cxx compiler. Can t cmake do it in a simple and normal way.
