CMAKE_IGNORE_PATH

Path to be ignored by FIND_XXX() commands.

the :command:`find_program`, :command:`find_library`, :command:`find_file`,

Specifies directories to be ignored by searches in FIND_XXX()
commands. This is useful in cross-compiled 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 that modules like FindX11 (and others) would
normally search. 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. If you want to ignore paths under
prefixes (bin, include, lib, etc.), you'll need to specify them
explicitly. See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH,
CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.
By default this is empty; it is intended to be set by the project.
