Cpp client supports visual studio 2026

[HTHou]

This pull request updates the build configuration and dependencies for the C++ client and its example, primarily to use the newer cmake-maven-plugin and improve compatibility with Windows environments, including the addition of Windows 2025 support. The most important changes are grouped below:

Build and Plugin Updates:

• Replaced the com.googlecode.cmake-maven-project plugin with io.github.cmake-maven-plugin across pom.xml, iotdb-client/client-cpp/pom.xml, and example/client-cpp-example/pom.xml, and updated the plugin version from 3.29.3-b2 to 4.2.3-b1 in the root pom.xml. [1] [2] [3] [4]
• Changed configuration property names from targetPath and buildDirectory to projectDirectory in plugin executions, and updated test skipping logic to use ${maven.test.skip} instead of ${ctest.skip.tests}. [1] [2] [3] [4]

Windows Build Improvements:

• Added windows-2025-vs2026 to the CI matrix in .github/workflows/multi-language-client.yml, and included a conditional step to use the Visual Studio 18 2026 CMake generator for this environment. [1] [2]
• Updated Windows-specific script properties in iotdb-client/client-cpp/pom.xml to reference scripts within a windows/ subdirectory.

Maven Wrapper Update:

• Upgraded the Maven wrapper version from 3.9.6 to 3.9.12 in .mvn/wrapper/maven-wrapper.properties.
