:command:`find_package` uses ``<PackageName>_ROOT`` variables.
|
||
|
|
|
||
|
|
In CMake 3.12 and above the :command:`find_package(<PackageName>)` command now
|
||
|
|
searches prefixes specified by the :variable:`<PackageName>_ROOT` CMake
|
||
|
|
variable and the :envvar:`<PackageName>_ROOT` environment variable.
|
||
|
|
Package roots are maintained as a stack so nested calls to all ``find_*``
|
||
|
|
commands inside find modules and config packages also search the roots as
|
||
|
|
prefixes. This policy provides compatibility with projects that have not been
|
||
|
|
updated to avoid using ``<PackageName>_ROOT`` variables for other purposes.
|
||
|
|
|
||
|
|
The ``OLD`` behavior for this policy is to ignore ``<PackageName>_ROOT``
|
||
|
|
variables. The ``NEW`` behavior for this policy is to use
|
||
|
|
``<PackageName>_ROOT`` variables.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.12. CMake version
|
||
|
|
|release| warns when the policy is not set and uses ``OLD`` behavior.
|
||
|
|
Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW``
|
||
|
|
explicitly.
