James E. King III resolved THRIFT-4560.
---------------------------------------
Resolution: Cannot Reproduce
Assignee: James E. King III
Fix Version/s: 1.0
Qt4 has been removed.
I checked and if -DWITH_QT5=ON is set, later on in
lib/cpp/src/thrift/qt/CMakeLists.txt there is a find_package for Qt5 with the
REQUIRED flag.
As such I see no issue that needs to be resolved.
> The logic of CMAKE_DEPENDENT_OPTION seems wrong and can break the build

> Project: Thrift

> The cmake build uses {{CMAKE_DEPENDENT_OPTION}} in several places. But
> according to my understanding, the resulting logic is wrong and can lead to
> problems. Consider the following example for building with Qt4 or Qt5 from
> {{build/cmake/DefineOptions.cmake}}:
> {noformat}
> find_package(Qt5 QUIET COMPONENTS Core Network)
> CMAKE_DEPENDENT_OPTION(WITH_QT5 "Build with Qt5 support" ON
> "Qt5_FOUND" OFF)
> {noformat}
> If a user configures thrift with {{cmake -DWITH_QT5=ON}} but does not have
> Qt5 installed, they will not get an error. They will just get a warning that
> the option {{WITH_QT5}} was unused.
> Furthermore, if the user disables Qt5 (i.e. because its broken), then {{cmake
> -DWITH_QT5=OFF}} will **not** disable the search for Qt5. If the
> {{find_package(Qt5 QUIET COMPONENTS Core Network)}} fails in error, the build
> will fail, despite the explicit request for {{cmake -DWITH_QT5=OFF}}.
> My expected behavior is that if {{WITH_QT5=OFF}} is specified, that no Qt5
> checks are run and that a missing/broken Qt5 would not impact thrift in any
> way.
