CMAKE_POLICY_WARNING_CMP0047
controls the warning for
policy CMP0047
.
CMAKE_POLICY_WARNING_CMP0056
controls the warning for
policy CMP0056
.
CMAKE_POLICY_WARNING_CMP0060
controls the warning for
policy CMP0060
.
CMAKE_POLICY_WARNING_CMP0065
controls the warning for
policy CMP0065
.
CMAKE_POLICY_WARNING_CMP0066
controls the warning for
policy CMP0066
.
CMAKE_POLICY_WARNING_CMP0067
controls the warning for
policy CMP0067
.
CMAKE_POLICY_WARNING_CMP0082
controls the warning for
policy CMP0082
.
CMAKE_POLICY_WARNING_CMP0089

policy CMP0126
.
CMAKE_POLICY_WARNING_CMP0128
controls the warning for
policy CMP0128
.
CMAKE_POLICY_WARNING_CMP0129

This variable should not be set by a project in CMake code. Project
developers running CMake may set this variable in their cache to
enable the warning (e.g. -DCMAKE_POLICY_WARNING_CMP<NNNN>=ON
).
Alternatively, running cmake(1)
with the
--debug-output
,
--trace
, or
--trace-expand
option will also
enable the warning.
