VSG build errors

[Dan Fenn]

Hello,

I'm trying to build VSG using the provided script, and I'm running into errors.

System configuration:

Chrono git hash 3f13de156a6597e9bd42f8a8be0a3370b4324683

RHEL 8

gcc 8.5.0 20210514

cmake version 3.26.5

buildVSG.sh configuration:

```

DOWNLOAD=ON

VSG_INSTALL_DIR="$HOME/codes/vsg"

BUILDSHARED=ON
BUILDDEBUG=OFF
BUILDSYSTEM="Unix Makefiles"

```

I receive the following error:

Hi Dan,

Could you please report your logs at very beginning in the output of buildVSG script in a txt file attached to the email? You should see something like the code below:

You need a newer version of CMake. 

The issue comes from the glslang package (for the newer VSG libraries, glslang must be explicitly built as the one in Vulkan may be too old). Although glslang requests a minimum CMake version of 3.22.1, they in fact need a newer CMake version.

Ah, thank you. I installed cmake 4.1, and that did fix that error. However, I'm now running into a different error:

[Radu Serban]

Da - you likely need to also upgrade your GCC compiler. Search the web for std::filesystem support in GCC. With that old of a version, that feature may be in 'experimental' or you may need to modify the script to explicitly request C++17 support. Much easier to just get a recent version of the compiler.

By the way, these are all glslang related problems. You may want to also check their GitHub issues page or a discussion forum if they have one.
