Cannot generate packages from system library

[MeteorsLiu]

For example, i want to generate libcurl which is installed in system library.

pkg-config --libs libcurl
-lcurl

Both llcppg and llcppcfg cannot recognize it, so i try to specify it mannually,

"libs": "-L/Library/Developer/CommandLineTools/SDKs/MacOSX15.0.sdk/usr/lib",

it cannot recognize it because of .dylib doesn't exist, however, there's a .tbd file representing .dylib in macOS.

nm -g /Library/Developer/CommandLineTools/SDKs/MacOSX15.0.sdk/usr/lib/libcurl.tbd

/usr/lib/libcurl.4.dylib (for architecture x86_64):

llcppg should search .tbd file when .dylib is not found.
