Replaces the QProcess->7z shim with the public-domain LZMA SDK (23.01) 7-Zip reader, vendored under sources/import/edz/lzma/ (decode-only subset). New edzsevenzip.cpp wraps SzArEx_Open/SzArEx_Extract and writes entries via Qt, so EdzArchive no longer needs an external 7-Zip at runtime. Enables the C language in CMake for the vendored sources. Verified: the bundled decoder extracts all three ifm sample .edz and the generated elements still match the Python oracle exactly (byte-correct decode), with no 7z on the path.

@brief Extracts an EPLAN Data Portal package (.edz) to a temporary folder.
|
|
|
|
A .edz is a 7-Zip archive holding a part definition (part.xml), an EPLAN
|
|
macro, a product image and metadata. EdzArchive unpacks it so the rest of the
|
|
import pipeline can read the (portable) part.xml.
|
|
|
|
Extraction uses the bundled (public-domain) LZMA SDK 7-Zip reader, so no
|
|
external 7-Zip is required at runtime (see edzsevenzip).
|
|
|
|
The extracted tree lives in a QTemporaryDir owned by this object and is
|
|
removed when the EdzArchive is destroyed.
