[question] wxWidgets requires gtk2-devel even gtk3-devel is installed

[kmreisi]

What is your question?

Hi all,

We use SLES 12 as build environment and using wxWdigets fails.

Error:

package gtk2-devel is not installed

ERROR: gtk/system: Error in system_requirements() method, line 45
zypper.install([f"gtk{self.options.version}-devel"], update=True, check=True)

ConanException: System requirements: 'gtk2-devel' are missing but can't install because tools.system.package_manager:mode is 'check'.Please update packages manually or set 'tools.system.package_manager:mode' to 'install' in the [conf] section of the profile, or in the command line using '-c tools.system.package_manager:mode=install'

Shouldn't the recipe detect hat gtk3-devel is available and use this automatically?

These are the packages we install:

        xvfb-run \
        xz \
        xz-devel \
        zlib-devel && \
    zypper -n clean -a

Is there a way / option to force the usage of gtk3 in our conanfile.py
