problem compiling on ubuntu 20.04

[jdfrankland]

Dear Florian, On an up-to-date Ubuntu 20.04 with the latest version of dev branch I got the following error when trying to compile. Can you help me please? Cheers John

Here are the exact steps I did:

git clone https://github.com/flueke/mvme.git
cd mvme && git checkout dev
git modules init && git modules update
cd .. && mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ../mvme
make -j8

The output of cmake is below.

For information: I have exactly the same error with the master branch. J

Hello John, this should be fixed in the latest revisions of both branches. There where some shared library dependency issues which for some reason did not cause problems on my dev system. Regards Florian

Closing as it should be fixed by now.
