ecbuild_warn_unused_files

Print warnings about unused source files in the project.

ecbuild_warn_unused_files()

If the CMake variable CHECK_UNUSED_FILES is set, ecBuild will keep track of any source files (.c, .cc, .cpp, .cxx) which are not part of a CMake target. If set, this macro reports unused files if any have been found. This is considered a fatal error unless UNUSED_FILES_LEVEL is set to a value different from ERROR.

Note

Enabling CHECK_UNUSED_FILES can slow down the CMake configure time considerably!
