C / C++ & CMake

CMake, Make, and compiler/linker errors - fixed.

Fix C/C++ CI failures: CMake configuration, Make errors, compiler and linker failures, and missing library/header issues.

CMake & Make

Configure, generate, build errors.

"Could NOT find <Package>"Fix CMake "Could NOT find <Package> (missing: <Package>_DIR)" in CI - a find_package() dependency is not "does not appear to contain CMakeLists.txt"Fix CMake "The source directory ... does not appear to contain CMakeLists.txt" in CI - wrong -S path, missing "Flow control ... not properly nested"Fix CMake "Flow control statements are not properly nested" in CI - an if/foreach/function block is missing "Invalid setting"Fix Conan "ERROR: Invalid setting X is not a valid 'settings.compiler.version' value" in CI - the profile "missing and no known rule to make it"Fix Ninja "error: X, needed by Y, missing and no known rule to make it" in CI - a build input does not exist

Link & libraries

Linker errors, missing libs.

"collect2: error: ld returned 1"Fix gcc "collect2: error: ld returned 1 exit status" in CI - a summary line that means the linker failed; the "undefined reference to std::filesystem"Fix ld "undefined reference to std::filesystem" in CI - older GCC/Clang ship filesystem in a separate library
