| Source file extensions must be explicit. | |
| In CMake 3.19 and below, if a source file could not be found by the name | |
| specified, it would append a list of known extensions to the name to see if | |
| the file with the extension could be found. For example, this would allow the | |
| user to run: | |
| .. code-block:: cmake | |
| add_executable(exe main) | |
| and put ``main.c`` in the executable without specifying the extension. | |
| Starting in CMake 3.20, CMake prefers all source files to have their extensions | |
| explicitly listed: | |
| .. code-block:: cmake | |
| add_executable(exe main.c) | |
| The ``OLD`` behavior for this policy is to implicitly append known extensions | |
| to source files if they can't be found. The ``NEW`` behavior of this policy is | |
| to not append known extensions and require them to be explicit. | |
