<PackageName>_ROOT¶
New in version 3.12.
This is a CMake Environment Variable. Its initial value is taken from the calling process environment.
Calls to find_package(<PackageName>) will search in prefixes
specified by the <PackageName>_ROOT environment variable, where
<PackageName> is the (case-preserved) 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 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 <PackageName>_ROOT CMake variable.
- <PACKAGENAME>_ROOT¶
New in version 3.27.
Calls to
find_package(<PackageName>)will also search in prefixes specified by the upper-case<PACKAGENAME>_ROOTenvironment variable. See policyCMP0144.
Note
Note that the <PackageName>_ROOT and <PACKAGENAME>_ROOT
environment variables are distinct only on platforms that have
case-sensitive environments.
