Calls to :command:`find_package(<PackageName>)` will search in prefixes
|
|
specified by the ``<PackageName>_ROOT`` environment variable, where
|
|
``<PackageName>`` is the name given to the ``find_package`` call
|
|
and ``_ROOT`` is literal. For example, ``find_package(Foo)`` will search
|
|
prefixes specified in the ``Foo_ROOT`` environment variable (if set).
|
|
See policy :policy:`CMP0074`.
|
|
|
|
This variable may hold a single prefix or a list of prefixes separated
|
|
by ``:`` on UNIX or ``;`` on Windows (the same as the ``PATH`` environment
|
|
variable convention on those platforms).
|
|
|
|
See also the :variable:`<PackageName>_ROOT` CMake variable.
