Basically it will consist in removing all references to the sift algorithm

• Remove Digeo/sift++ references
• Use Akaze as feature detector
• Maybe use Tarapio instead of Tapas

I've been working on trying to create the makefiles of micmac, and keep getting similar errors about QT5. Before trying to create the makefiles/compile, I checked the dependencies, which proved successful.

Here's what I tried to do after creating and entering the build directory.

`build $ cmake ../
-- -----> OpenGL found
CMake Error at /usr/local/Cellar/qt/5.14.2/Qt5WidgetsConfig.cmake:94 (find_package):
Could not find a package configuration file provided by "Qt5Gui" (requested
version 5.14.2) with any of the following names:

Qt5GuiConfig.cmake
qt5gui-config.cmake

Add the installation prefix of "Qt5Gui" to CMAKE_PREFIX_PATH or set
"Qt5Gui_DIR" to a directory containing one of the above files. If "Qt5Gui"
provides a separate development package or SDK, be sure it has been
installed.
Call Stack (most recent call first):
CMakeLists.txt:209 (find_package)

-- Configuring incomplete, errors occurred!`

I installed QT using brew, so I believe that it is installed unless I need to do something else. I also tried to set it to CMAKE_PREFIX_PATH and that also returned the same thing.

`build $ cmake ../ -DWITH_QT5=1 -DCMAKE_PREFIX_PATH=/usr/local/Cellar/qt/5.14.2/lib/cmake/Qt5Gui/Qt5GuiConfig.cmake
-- -----> OpenGL found

When looking around I also found this report which refers to a problem with previous versions of Xcode and apparently this particular problem has been going on for some time. I was thinking they could be related:
https://trac.macports.org/ticket/58378

here is the CMakeOutput.log:
