ENable autodeploy of assets into bin folder - #60

WalkthroughThe build now copies runtime assets into configuration-specific output directories. Image and font paths include asset subdirectories. ChangesRuntime assets and backend updates
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This change can leave sample assets unavailable in single-configuration builds; the resulting font-load failure can crash text rendering. Align the asset output layout, handle failed font loads, and resolve the outstanding CMake compatibility concern before merging.

“/assets” so button_test.png is copied directly into the runtime output

CMake add_custom_target COMMENT generator expressions supported since which version official documentation
💡 Result:
The use of generator expressions in the COMMENT argument of the CMake add_custom_target command is supported beginning with CMake version 3.26 [1][2][3][4]. Prior to this version, generator expressions were not expanded within the COMMENT field [5].

CMake RUNTIME_OUTPUT_DIRECTORY multi-configuration generators automatic configuration subdirectory single-configuration generator official documentation
💡 Result:
In CMake, the behavior of RUNTIME_OUTPUT_DIRECTORY differs between multi-configuration and single-configuration generators regarding how they manage output paths [1][2]. Official documentation states that for multi-configuration generators (such as Visual Studio, Xcode, and Ninja Multi-Config), CMake automatically appends a per-configuration subdirectory (e.g., /Debug or /Release) to the path specified in RUNTIME_OUTPUT_DIRECTORY [2]. This automatic behavior is suppressed if the specified directory path contains a generator expression (e.g., "$<...>") [2]. In contrast, single-configuration generators do not append such subdirectories automatically [1]. To achieve consistent behavior or precise control across both types of generators, developers frequently employ the following strategies: 1. Using Generator Expressions: By incorporating a generator expression like

Align the asset destination with the sample output directory.
For a single-configuration generator with CMAKE_BUILD_TYPE=Release, tiny_ui_sample is placed in bin/tiny_ui_sample, but tiny_ui_copy_assets copies assets to bin/Release. Relative paths such as fonts/... and images/button_test.png can therefore fail when the sample runs from bin. Use the same output layout for the targets and asset copy for every generator.
