Upstream GLSLang releases no longer detected by QuickBuild #16571
Description
Beginning with GLSL v14.0.0 (released 2023-12-21), the legacy HLSL and OGLCompiler stub libraries were completed removed from the upstream buildsystem. This is causing compilations with the --enable-glslang flag explicitly set to error out after failing to locate those libraries, despite a complete and functioning GLSL installation being present on the system. Currently both Debian Unstable and Ubuntu 24.04 LTS "Noble Numbat" are shipping with GLSL ⩾14.0.0.
Expected behavior
QuickBuild tests for the presence of GLSL using the upstream linking information published with pkgconf and/or CMake. (Ironically, I believe I saw a notice in their release notes that they have also ceased supporting pkgconf and now only officially support linking through the CMake buildsystem.) Based on my cursory inspection of QuickBuild, it is brittle in this instance because it manually tests for the presence of each of the (former) GLSL constituent libraries rather than querying one of the above-mentioned tools and accepting the linker flags supplied therein. (To wit, QB test for libOGLCompiler and QB test for libHLSL)

--------------------------------------------------------------------------------Steps to reproduce the bug
- Prepare a RetroArch build environment on Debian Sid or Ubuntu 24.04 LTS "Noble Numbat."
- Verify that the appropriate packages needed to link RetroArch to GLSL are installed prior to configuring the build system (i.e.
[sudo] apt -y install glslang-dev). - Make the RetroArch source tree your working directory and invoke the configure script with the flag
--enable-glslang.
