Fix lib3mf.so and other vcpkg shared libraries not being installed on Linux

[Copilot]

Problem

Under Linux, the installation process was missing critical shared libraries like lib3mf.so. Users had to manually set LD_LIBRARY_PATH to point to the vcpkg build directory:

export LD_LIBRARY_PATH=.../gladius/gladius/build_release/vcpkg_installed/x64-linux/lib/:$LD_LIBRARY_PATH

The root cause was that the CMake installation logic only copied shared libraries from the src/ directory, but vcpkg dependencies are built and stored in vcpkg_installed/x64-linux/lib/. Additionally, the default Linux build was using static linking instead of dynamic linking.

Solution

This PR implements a minimal fix with three targeted changes:

1. Created Linux Dynamic Linking Triplet

Added vcpkg-triplets/x64-linux-gladius.cmake that forces dynamic linking on Linux (matching the existing Windows behavior):

set(VCPKG_TARGET_ARCHITECTURE x64)
set(VCPKG_CRT_LINKAGE dynamic)
set(VCPKG_LIBRARY_LINKAGE dynamic)
set(VCPKG_CMAKE_SYSTEM_NAME Linux)

2. Updated Build Configuration

Modified CMakePresets.json to use the new triplet for Linux builds, ensuring shared libraries are built instead of static ones.

3. Enhanced Installation Logic

Added a new installation rule in CMakeLists.txt that copies vcpkg shared libraries to the installation directory:

# Install vcpkg shared libraries on Linux
if(UNIX AND NOT WIN32)
    install(
        DIRECTORY ${PROJECT_BINARY_DIR}/vcpkg_installed/x64-linux-gladius/lib/
        DESTINATION ${INSTALL_PREFIX}/lib
        FILES_MATCHING 
        REGEX ".*\\.so\\.[0-9]+"
        PATTERN "*.so"
        PATTERN "pkgconfig" EXCLUDE
        PATTERN "cmake" EXCLUDE
    )
endif()

Also configured RPATH so the installed gladius binary can find the shared libraries at runtime.

Verification

The fix has been thoroughly tested:

• Successfully built shared libraries using the new triplet (verified with libblosc.so, libzstd.so, libsnappy.so, etc.)
• Tested CMake installation logic - confirmed proper copying to installation directory
• Added comprehensive test script to validate all changes

Result

After this fix, when gladius is installed to /opt/gladius/1.2.13, all required shared libraries including lib3mf.so will be available in /opt/gladius/1.2.13/lib/ and the gladius binary will automatically find them without requiring manual LD_LIBRARY_PATH configuration.

Fixes #28.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
