How to set link option.
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.

My cmake project builds an executable consisting of c and c source files.
Hi chenli thanks for the question.
Option honors normal variables.
Active 2 months ago.
This would lead to some strange behavior that the configuration between two cmake runs would be different.
In this case the set command will add the type.
These settings enable you to set cmake variables and save them in cmakesettings json.
For example compiling the cpp file requires the std c 11 flag but gcc does not recognise that flag and so it should not be used for the c file.
If hello h is the file that uses a c 14 feature then the project where it belongs to should specify that requirement.
However there are cases in which a normal non cached variable of the same name as the option may be defined by the project prior to calling the option command.
When executing cmake configuration for the second time the option command would be ignored because there is already a value in the cache and the value from the set command would be used.
Set opencv enable nonfree cmake option and rebuild the library in function create.
In this case i d edit src cmakelists txt where the hello lib target is defined as that s where hello h belongs to.
Any pointer about what i m doing wrong is really welcome.
For example a project that embeds another project as a subdirectory may want to hard.
