CMAKE_IGNORE_PATH

Semicolon-separated list of directories to be ignored by the find_program(), find_library(), find_file(), and find_path() commands. This is useful in cross-compiling environments where some system directories contain incompatible but possibly linkable libraries. For example, on cross-compiled cluster environments, this allows a user to ignore directories containing libraries meant for the front-end machine.

By default this is empty; it is intended to be set by the project. Note that CMAKE_IGNORE_PATH takes a list of directory names, not a list of prefixes. To ignore paths under prefixes (bin, include, lib, etc.), specify them explicitly.

See also the CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH, and CMAKE_PROGRAM_PATH variables.
