Problems with gtk installation when executing build.sh

[alexkrz]

Hello,

I am trying to build the project on Ubuntu 20.04 with cmake 3.26.4 and conan 2.0.17. When I execute build.sh, conan wants to install libgtk2.0-dev on system level. I am wondering whether it is possible to perform the build without installing additional packages on system level?

Below you can find the output after executing build.sh:

using conan file conanfile.txt

I get the following error: dpkg-query: no packages found matching libgtk2.0-dev

I have checked why libgtk is listed as a requirement, and it comes from opencv. We definitely do not use it, and we should explicitly deactivate it in conanfile.txt in opencv options:

[options]
opencv*:with_gtk=False
opencv*:with_qt=False

We'll create a pull request.

@alexkrz please check if it works for you

Thanks for addressing the issue so quickly! Now I am able to proceed with the installation without sudo rights. However, I am running into the next problem: CMake Error at {Home}/miniconda3/envs/ofiq/share/cmake-3.26/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find LAPACK (missing: LAPACK_LIBRARIES)

Edit: I guess it makes sense to open another issue here. I'll do that now.
