How to build OpenMesh?

I am building OpenMesh on a Gentoo machine, which used to work a few years back. But now, with the following commands ...

git clone https://www.graphics.rwth-aachen.de:9000/OpenMesh/OpenMesh.git 
$ cd OpenMesh
$ mkdir build
$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/openmesh ..
$ make
$ make install

... I am getting these errors:

$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/openmesh ..

-- Configuring incomplete, errors occurred!

My understanding is that these files (VCICommon, VCIOutput, VCIQT) are other CMake files. I'm not understanding what I'm missing.

Can anyone help out?

Solution

  • The CMake files VCICommon, VCIOutput, VCIQT, etc. are now contained in a Git submodule of OpenMesh. You need to clone with Git submodules (--recursive), i.e.

    git clone --recursive https://www.graphics.rwth-aachen.de:9000/OpenMesh/OpenMesh.git

    Or, if you've already cloned a repository without specifying the --recursive option, you can do

    git submodule update --init --recursive
