CMAKE_EXPORT_COMPILE_COMMANDS — CMake 4.2.6 Documentation

# CMAKE_EXPORT_COMPILE_COMMANDS

Added in version 3.17.

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

The default value for `CMAKE_EXPORT_COMPILE_COMMANDS` when there is no explicit configuration given on the first run while creating a new build tree. On later runs in an existing build tree the value persists in the cache as `CMAKE_EXPORT_COMPILE_COMMANDS`.
