# COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>

Added in version 3.1.

Per-configuration output directory for the MS debug symbol `.pdb` file generated by the compiler while building source files.

This is a per-configuration version of `COMPILE_PDB_OUTPUT_DIRECTORY`, but multi-configuration generators (Visual Studio, `Xcode`, `Ninja Multi-Config`) do NOT append a per-configuration subdirectory to the specified directory. This property is initialized by the value of the `CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>` variable if it is set when a target is created.

Added in version 3.12: Contents of `COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>` may use `generator expressions`.

Note

The compiler-generated program database files are specified by the `/Fd` compiler flag and are not the same as linker-generated program database files specified by the `/pdb` linker flag. Use the `PDB_OUTPUT_DIRECTORY_<CONFIG>` property to specify the latter.
