Use ``QCC`` compiler id for the qcc drivers on QNX.
|
||
|
|
|
||
|
|
CMake 3.0 and above recognize that the QNX qcc compiler driver is
|
||
|
|
different from the GNU compiler.
|
||
|
|
CMake now prefers to present this to projects by setting the
|
||
|
|
:variable:`CMAKE_<LANG>_COMPILER_ID` variable to ``QCC`` instead
|
||
|
|
of ``GNU``. However, existing projects may assume the compiler id for
|
||
|
|
QNX qcc is just ``GNU`` as it was in CMake versions prior to 3.0.
|
||
|
|
Therefore this policy determines for QNX qcc which compiler id to
|
||
|
|
report in the :variable:`CMAKE_<LANG>_COMPILER_ID` variable after
|
||
|
|
language ``<LANG>`` is enabled by the :command:`project` or
|
||
|
|
:command:`enable_language` command. The policy must be set prior
|
||
|
|
to the invocation of either command.
|
||
|
|
|
||
|
|
The OLD behavior for this policy is to use the ``GNU`` compiler id
|
||
|
|
for the qcc and QCC compiler drivers. The NEW behavior for this policy
|
||
|
|
is to use the ``QCC`` compiler id for those drivers.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.0. Use the
|
||
|
|
:command:`cmake_policy` command to set this policy to OLD or NEW explicitly.
|
||
|
|
Unlike most policies, CMake version |release| does *not* warn
|
||
|
|
by default when this policy is not set and simply uses OLD behavior.
|
||
|
|
See documentation of the
|
||
|
|
:variable:`CMAKE_POLICY_WARNING_CMP0047 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
|
||
|
|
variable to control the warning.
