I'm trying to install the pip3 python package wxpython which fails due to

libgl-dev referes to libgl1-mesa-dev which is already installed as well as libglw1-mesa-dev which seems the only other possible candidate based on the auto-completion of sudo apt-get install libgl.

The installation with pip for Python 2.x succeeds.

This is rather two questions. If I take your question literally, an approach would be using apt-file to search for packages containing the file you are looking for:

$ apt-file search libGL.so
libgl1: /usr/lib/x86_64-linux-gnu/libGL.so.1
libgl1: /usr/lib/x86_64-linux-gnu/libGL.so.1.0.0
libglvnd-dev: /usr/lib/x86_64-linux-gnu/libGL.so
nvidia-340: /usr/lib/i386-linux-gnu/libGL.so
nvidia-340: /usr/lib/i386-linux-gnu/libGL.so.1
nvidia-340: /usr/lib/i386-linux-gnu/libGL.so.340.106
nvidia-340: /usr/lib/x86_64-linux-gnu/libGL.so
nvidia-340: /usr/lib/x86_64-linux-gnu/libGL.so.1
nvidia-340: /usr/lib/x86_64-linux-gnu/libGL.so.340.106
primus-libs: /usr/lib/x86_64-linux-gnu/primus/libGL.so.1
virtualbox-guest-x11: /usr/lib/virtualbox/additions/libGL.so
virtualbox-guest-x11: /usr/lib/virtualbox/additions/libGL.so.1
virtualbox-guest-x11-hwe: /usr/lib/virtualbox/additions/libGL.so
virtualbox-guest-x11-hwe: /usr/lib/virtualbox/additions/libGL.so.1

If you haven't got apt-file installed, install it and initialise its database first using:

$ sudo apt install apt-file
$ sudo apt-file update

To check if the linker can actually find the installed library, run this:

$ ldconfig -p | grep libGL.so
libGL.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libGL.so.1
libGL.so.1 (libc6) => /usr/lib/i386-linux-gnu/libGL.so.1
libGL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libGL.so

As to why the wxPython build using pip3 is not picking up either of them is a question I can not answer.

I had the same problem.
apt said that libgl1-mesa-dev was already installed, but I couldn't find a package in /var/cache/apt.

This helped:

sudo apt-get remove --purge libgl1-mesa-dev

(After this, DO NOT make a sudo apt autoremove.)

sudo apt-get install libgl1-mesa-dev

After this compiling worked.
