If your project targets multiple platforms and compilers this can be a headache to set up.
Cmake set c version.
Option use debug enter debug mode off now we can set this option to on when running cmake.
The following screenshot of the extension shows a logical view of the open source cmake project bullet3 organized by target left and several cmake specific commands.
This property is initialized by the value of the cmake cxx standard variable if it is set when a target is created.
Then we ll use cmake s add definitions function to set the corresponding preprocessor flag in our c program.
First we will use cmake s option function to add a command line option when running the cmake command.
Updated june 2020 with the constant evolution of c build systems have had to deal with the complication of selecting the relevant compiler and linker flags.
Cmake evaluates the environment variables cc for the c compiler cxx for the c compiler and fc for the fortran compiler.
How can i force cmake to generate the makefiles for a specific vs version.

Sets the name of the project and stores it in the variable project name when called from the top level cmakelists txt also stores the project name in the variable cmake project name.
These will add the needed compile options on targets e g.

Happily with features added in cmake 3 1 it is trivial to handle this.
The version can be made a requirement by setting to on the variables cmake c standard required and cmake cxx standard required respectively.
We recommend using the cmake tools extension alongside the c c extension for visual studio code for intellisense configuration and a full fidelity c c development experience.
Also sets the variables.
See the cmake compile features 7 manual for information on compile features and a list of supported compilers.
