Make the contacts examples slightly more standalone

[pinotree]

Instead of symlinking the scripts directory in the grantlee sources to the source directory of this example, directly invoke the extract_strings_linguist.py script with its relative path for the example source directory.

The linguist_ts target still depends on something outside of it, however now it is possible to build the contacts example on its own, even when it is copied as standalone out of the grantlee sources.

@steveire hi, can you please take a look at this PR? Thanks in advance

[steveire]

@pinotree Hi, sorry for the delay.

${CMAKE_SOURCE_DIR}/../../ doesn't seem very standalone to me. Perhaps a cmake variable for the path should be used instead if present?

What motivates this? Is it an attempt to (debian-)package grantlee examples separate to the binaries?

${CMAKE_SOURCE_DIR}/../../ doesn't seem very standalone to me. Perhaps a cmake variable for the path should be used instead if present?

Yes, I know that, and I explained the reason of the change in the commit message. ${CMAKE_SOURCE_DIR}/../../ is now used only for the linguist_ts target, which is not run by default. Hence, with this PR you can build the example as-is, as long as you don't manually invoke the linguist_ts target.

What motivates this? Is it an attempt to (debian-)package grantlee examples separate to the binaries?

Yes, we do ship the examples/ subdirectory as-is as part of the -dev package of grantlee.

@steveire ping?

@pinotree When I was last trying to do something about this I was looking for you on IRC or another chat server. I didn't find you. Do you use any?
