HOMEPAGE_URL causes problems in Ubuntu 18.04 (3.0.1)

[AlexisWilke]

Describe the bug
Trying to compile the project fails because it doesn't view HOMEPAGE_URL as one of the project() options.

Here is the documentation of the version available on Ubuntu 18.04: https://cmake.org/cmake/help/v3.10/command/project.html

I would imagine that you'd still want to support that older version of Ubuntu since it's still valid.

Expected behavior
Not break the build process.

Reproduction steps
Install an older version of cmake.

$ cmake --version
cmake version 3.10.2

Then try building as usual. The HOMEPAGE_URL text is going to be included in the project name (or something of the sort) and cmake fails.

Platform information:

• OS: Ubuntu 18.04
• Compiler+version: g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0 (no issue here)
• Catch version: v3.0.1

Additional Info:
FYI: Ubuntu 20.04 has cmake version 3.16.3 which supports HOMEPAGE_URL.
