This PR is an update to #873 which adds Freetype font support to
PutText().The original work was done by @lz1998 back in 2021 but the PR has became stale due to build issues with freetype fonts on Windows. I have modified the original PR to limit building to Linux only as the build issues on Windows should not block this important feature which supports text for non ascii characters.
This PR stops the need for workarounds as discussed in #749 to support Chinese text or at #1150.
Merging of this PR should close off #873 and #874.
Windows
OpenCV may have now fixed the build issues on Windows here microsoft/vcpkg#27343 so any Windows users who require this feature can confirm that and submit another PR.
To remove the Linux only build restrictions.
