+CMAKE_EXPORT_COMPILE_COMMANDS
+-----------------------------
+
+.. include:: ENV_VAR.txt
+
+The default value for :variable:`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 :variable:`CMAKE_EXPORT_COMPILE_COMMANDS`.

+CMAKE_<LANG>_COMPILER_LAUNCHER
+------------------------------
+
+.. include:: ENV_VAR.txt
+
+Default compiler launcher to use for the specified language. Will only be used
+by CMake to initialize the variable on the first configuration. Afterwards, it
+is available through the cache setting of the variable of the same name. For
+any configuration run (including the first), the environment variable will be
+ignored if the :variable:`CMAKE_<LANG>_COMPILER_LAUNCHER` variable is defined.
