Hi

CMake Warning (dev) in CMakeLists.txt:

  disabled.  Consider adding:

    find_package(Qt<QTVERSION> COMPONENTS Core)

  to your CMakeLists.txt file.
This warning is for project developers.  Use -Wno-dev to suppress it.

Any tips ? I'm on Ubuntu 22.043

qmake --version QMake version 3.1 Using Qt version 5.15.3 in /usr/lib/x86_64-linux-gnu

Gencolormap uses the CMake build system instead of qmake, and it requires Qt6 instead of Qt5.

So, with package qt6-base-dev, something like the following should work:

cd gencolormap
mkdir build
cd build
cmake ..
make

[adammaj1]

sudo apt-get install qt6-base-dev
cd gencolormap
mkdir build
cd build
cmake ..
make

and it works. Thx
