Linking failed when building with CMake 3.14

[HJarausch]

Trying to build the version it fails with lots of undefined references like
wxGLCanvas::GetClassInfo() const

It should build against additional libraries like libwx_gtk2u_aui-3.0

The CMake build system should be take care of the needed wxWidgets libs.
We are currently at beta 2 and there were reports that it builds fine on different systems without problems.

CMake is using wx-config to get the needed libs.
What is the output of "wx-config --selected-config" and "wx-config --libs all"?
I'm getting here:
>wx-config --selected-config
gtk2-unicode-3.0
>wx-config --libs all
-L/usr/lib/i386-linux-gnu -pthread -lwx_gtk2u_xrc-3.0 -lwx_gtk2u_stc-3.0 -lwx_gtk2u_richtext-3.0 -lwx_gtk2u_ribbon-3.0 -lwx_gtk2u_propgrid-3.0 -lwx_gtk2u_aui-3.0 -lwx_gtk2u_gl-3.0 -lwx_gtk2u_media-3.0 -lwx_gtk2u_html-3.0 -lwx_gtk2u_qa-3.0 -lwx_gtk2u_adv-3.0 -lwx_gtk2u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0

Maybe there are missing some wxWidgets libs on your side or the configuration is not corrupted. (Please state also which Hugin version and some details about the systems, e.g. which wxWidgets version.)

Someone from the GenToo community solved this problem
by replacing (in CMakeLists.txt)
FIND_PACKAGE(wxWidgets REQUIRED)
by
FIND_PACKAGE(wxWidgets REQUIRED base core aui xrc html xml adv gl net qa)

That's strange. I checked CMake 3.14 release. It still supports wxWidgets_USE_LIBS.
Does Gentoo apply some changes to share/cmake-3.xx/Modules/FindwxWidgets.cmake in the CMake package or otherwise? Otherwise I don't know why it does not work on your side.

We have the same problem on fedora, all releases. Hugin no longer builds when cmake is upgraded from 3.13.4 to 3.14.0:

[Bruno Postle (brunopostle)]

The fedora problem is with the 2018.0.0 release, this is something that has changed in cmake.

Okay, I fixed the CMake as proposed by in the Gentoo bug tracker.
